Synthesis and Photophysical Properties of α-(N-Biphenyl)-Substituted 2,2'-Bipyridine-Based Push-Pull Fluorophores.

ABSTRACT: A series of new α-(N-biphenyl)-substituted 2,2'-bipyridines were obtained through the combination of the ipso-nucleophilic aromatic substitution of the C5-cyano group, aza-Diels-Alder and Suzuki cross-coupling reactions, starting from 5-cyano-1,2,4-triazines. For the obtained compounds, photophysical and fluorosolvatochromic properties were studied. Fluorophores 3l and 3b demonstrated unexpected AIEE activity, while 3a and 3h showed promising nitroexplosive detection abilities.

Photophysical and Electrical Properties of Highly Luminescent 2/6-Triazolyl-Substituted Push-Pull Purines.

Project description:New push-pull N(9)-alkylated 6-piperidino-2-triazolylpurine and 2-piperidino-6-triazolylpurine derivatives are synthesized, and their optical and optoelectronic properties are comprehensively characterized with experimental and computational methods. The compounds possess intense violet or blue fluorescence with fluorescence quantum yields of up to 91% in solution and 40% in host-free films. Depending on their structural composition, the compounds have ionization energy in the range of 5.25-6.04 eV, electron affinity of 2.18-3.15 eV, and triplet energy of 2.52-2.95 eV. Due to the presence of hole-transporting purine and electron-transporting triazole fragments, compounds exhibit bipolar charge-transportation ability. Despite the favorable emissive properties of the studied push-pull purines, their electroluminescence in thin films is quenched owing to large current densities that are present even at a moderate driving voltage. This marks application directions related to a predominantly charge-transportation functionality as the most suitable for this compound class.

Synthesis, photophysical and nonlinear optical properties of push-pull tetrazoles.

Project description:A 2,5-disubstituted tetrazole with p-nitrophenyl and 3-pyridyl units as acceptors (1a), and three push-pull tetrazoles with p-nitrophenyl as an acceptor and phenyl (1b), 2-(dibenzo[b,d]furan-4-yl) (1c), and 4-(N,N-diphenylamino)phenyl (1d) as donor groups, were synthesized by copper-catalyzed aerobic C-N coupling of p-nitrophenyl tetrazole with appropriately substituted aryl boronic acids. The absorption and emission spectra of 1a-c showed minimal dependence on the polarity of the solvent; however, in the case of 1d a blue shift was noted in the longest absorption band (λ 1) as the polarity increased. The fluorescence intensity of the title compounds was found to be solvent-dependent; however, no apparent correlation to solvent polarity could be established. The absorption and emission characteristics of 1a-d were also influenced by the nature of the substituent as 1d, bearing a strong electron donating 4-(N,N-diphenylamino)phenyl group, displayed a significant red shifted absorption (λ 1) as well as emission (λ em) bands compared to other compounds. Time dependent density functional calculations (CAM-B3LYP/6-311++G**) revealed that the longest wavelength band (λ 1) is associated with an intramolecular charge transfer (ICT) from HOMO/HOMO-1/HOMO-2 → LUMO/LUMO+1 in these molecules. The first hyperpolarizability values, β HRS, of 1a-d were measured using the solution-based hyper-Rayleigh scattering technique using a femtosecond Ti:Sapphire laser and the highest NLO activity was measured for 1d with the greatest push-pull characteristics. A strong correlation was observed between the calculated hyperpolarizability (β tot) and experimentally measured values (β HRS).

Isoelectronic Push-Pull Fluorescent Difluoroborates: Halogen Bonding and Photophysical Properties.

Project description:The structural and photophysical properties in the halogen bonding environment were thoroughly studied for a newly synthesized series of fluorescent dyes and their model derivatives. The analysis revealed that the ground-state interactions among both series are likewise. The fluorescent dyes have push-pull topology, and there is a low-lying charge-transfer (CT) excited state in their electronic structure. In order to study the effect of intermolecular interactions on the photophysical parameters of the CT excited state, a palette of solvents was used (C6F6, C6F5Cl, C6F5Br, and C6F5I). Our studies revealed that the weak halogen bonding between the perfluorohaloarene solvent and the heterocyclic core of the dyes enhances the CT in their excited states. The results also demonstrated that the position of the heterocyclic nitrogen atom in the acceptor core simultaneously controls the directionality of the intermolecular interaction and influences both the emission wavelength and the fluorescence quantum yield. Experimental data were further supported by the results of quantum-chemical calculations. Overall, the study establishes a direct link between the topology of a moiety prone to specific intermolecular interactions and the photophysical properties of fluorescent probes.

Bis(?-biphenyl-2,2'-dicarboxyl-ato)bis-[(2,2'-bipyridine)copper(II)].

Project description:The title compound, [Cu(2)(C(14)H(8)O(4))(2)(C(10)H(8)N(2))(2)], is a centrosymmetric binuclear copper(II) complex, with a Cu?Cu separation of 6.136?(16)?Å. The Cu atom displays a cis-CuN(2)O(2) square-planar geometry, although two long (> 2.43?Å) Cu?O contacts complete a distorted cis-CuN(2)O(4) octa-hedron. Extensive C-H?O hydrogen bonds link the mol-ecules into a three-dimensional network.

Bis(μ-biphenyl-2,2'-dicarboxyl-ato)bis-[(2,2'-bipyridine)copper(II)].

Project description:The title compound, [Cu(2)(C(14)H(8)O(4))(2)(C(10)H(8)N(2))(2)], was obtained by solvothermal synthesis. The Cu(II) atom is coordinated by one chelating 2,2'-bipyridine ligand and two carboxyl groups from different biphenyl-2,2'-dicarboxyl-ate ligands, leading to a distorted octahedral environment. Each carboxyl-ate group makes one short Cu-O bond [1.9608 (14) and 1.9701 (14) Å] and one longer Cu-O contact [2.4338 (17) and 2.5541 (17) Å] to each Cu(II) atom. The biphenyl-2,2'-dicarboxyl-ate ligands bridge between Cu(II) atoms, forming a dinuclear complex around a crystallographic inversion centre.

Bis(μ-biphenyl-2,2'-dicarboxyl-ato)bis-[(2,2'-bipyridine)cobalt(II)].

Project description:In the title compound, [Co(2)(C(14)H(8)O(4))(2)(C(10)H(8)N(2))(2)], the Co(II) atom is coordinated by two N atoms from one 2,2'-bipyridine ligand and two O atoms from two biphenyl-2,2'-dicarboxyl-ate (2,2'-dpa) ligands in a distorted planar geometry. Longer Co-O contacts [2.437 (3) and 2.552 (3) Å] are formed to the second O atom of each coordinated carboxyl-ate group so that these groups approximate a bidentate coordination mode and the coordination geometry around Co(II) approaches distorted octa-hedral. The 2,2'-dpa ligands bridge two Co(II) atoms, forming a cyclic dinuclear complex around a centre of inversion.

Project description:In the centrosymmetric dinuclear mol-ecule of the title compound, [Cd(2)(C(14)H(8)O(4))(2)(C(10)H(8)N(2))(2)(H(2)O)(2)], the Cd(2+) ion is coordinated by three O atoms from two different diphenyl-dicarboxyl-ate (dpa) ligands (one O,O'-bidentate and one monodentate), a chelating bipyridine ligand and a water mol-ecule, generating an extremely distorted trigonal-prismatic (or irregular) CdN(2)O(4) coordination geometry for the metal ion. The bridging ligands generate an 18-membered ring, which is stabilized by two pairs of intra-molecular O-H⋯O hydrogen bonds.

Synthesis and Optical Characterization of Hydrazone-Substituted Push-Pull-Type NLOphores.

Project description:Two distinct families of NLOphores featuring hydrazone donors were synthesized using click-type [2 + 2] cycloaddition retroelectrocyclizations (CA-RE). Despite the limitations in the substrate scope, it was shown for the first time that hydrazone-activated alkynes could undergo reactions with TCNE/TCNQ. The electrochemical, photophysical, and second-order nonlinear optical (NLO) characteristics of the chromophores were analyzed utilizing experimental and computational approaches. Chromophores 17-21 and 23-27 exhibited two reduction waves, along with one oxidation wave that can be attributed to the hydrazone moiety. All chromophores exhibit charge-transfer bands extending from the visible to the near-infrared region. The λmax of hydrazone-based chromophores falls within the range of 473 to 725 nm. Additionally, all chromophores exhibited positive solvatochromism. Computational studies have been performed to elucidate the origin of the low-energy absorption bands. Parameters such as dipole moment, band gaps, electronegativity, global chemical hardness/softness, average polarizability, and first hyperpolarizability were calculated to obtain information about NLO properties of the target structures. The thermal stabilities of the NLOphores were assessed through TGA. Experimental NLO measurements were conducted using the electric field-induced second harmonic generation (EFISHG) technique. The studied structures demonstrated NLO responses, with μβ values between 520 × 10-48 esu and 5300 × 10-48 esu.

Preparation and photophysical properties of quinazoline-based fluorophores.

Project description:The donor-acceptor design is a classic method of synthesizing new fluorescent molecules. In this study, a series of new fluorescent compounds (1-10) were synthesized based on 2-(3,5-bis(trifluoromethyl)phenyl)-quinazoline acceptor and various amino donors. The fluorescent emissions of 1-10 cover the spectrum from 414 nm to 597 nm in cyclohexane solutions with various amino donors on 4- or 7-positions of quinazoline. Ultimately, compounds 1 and 2 presented the highest photoluminescence quantum yield (QY) over 80%, while compound 10 provided the largest Stokes shift (161 nm) in cyclohexane. Most of them have strong emissions in aggregated states such as in nanoparticles, in powders, in crystals and in films. Mechanochromic properties were observed for compounds 1, 2, 4 and 7. Furthermore, blue OLEDs were fabricated by using compound 2 or 7 as the active layer.

α- and β-Substituted Metal-Free Phthalocyanines: Synthesis, Photophysical and Electrochemical Properties.

Project description:Two novel phthalonitrile derivatives, bearing two hexyloxy groups and a benzodioxin (or a naphthodioxin) annulated ring, along with their corresponding metal-free phthalocyanines (H2Pc) were prepared. FT-IR, mass, electronic absorption, 1H NMR, and 13C NMR spectroscopy were employed for the characterization of all compounds. The effect of hexadeca substituents on the photophysical properties of metal-free Pcs was investigated. Photophysical properties of H2Pc were studied in tetrahydrofuran (THF). Fluorescent quantum yields of phthalocyanines (Pcs) were calculated and compared with the unsubstituted phthalocyanine. 1,4-Benzoquinone effectively quenched the fluorescence of these compounds in THF. Cyclic and square wave voltammetry methods were applied to metal-free phthalocyanines and Pc-centered oxidation and reduction processes were obtained.
