Synthesis and Properties of a Bay-Annulated-Indigo Tetramer Based on Low-Cost Spiro[Fluorene-9,9'-Xanthene] Core.

ABSTRACT: A three-dimensional bay-annulated-indigo (BAI) tetramer has been prepared by appending BAI units onto a low-cost spiro[fluorene-9,9'-xanthene] (SFX) core. The target compound 4BAI-SFX exhibits strong and broad absorption in the visible region covering the range of 450~700 nm. The electrochemical measurement illuminates the characteristics of a deep lowest unoccupied molecular orbital (LUMO) level and multiple redox states of 4BAI-SFX. These results suggest that 4BAI-SFX should be a selectable electron-transporting material for eco-friendly organic semiconductors.

2,7-Dibromo-9,9-dimethyl-9H-fluorene.

Project description:The title mol-ecule, C(15)H(15)Br(2), has crystallographic m2m site symmetry. As a result, all atoms, except for those of the methyl groups, are exactly coplanar. In the crystal structure, there are weak ?-? inter-actions with a centroid-centroid distance of 3.8409?(15)?Å between symmetry-related mol-ecules, which stack along the c axis.

2,2'-Bi(9,9-di-ethyl-fluorene).

Project description:The title compound, C34H34, systematic name 9,9,9',9'-tetra-ethyl-2,2'-bi(9H-fluorene), crystallized with two crystallographically independent mol-ecules (A and B) in the asymmetric unit. These differ mainly in the orientation of the lateral ethyl chains: in mol-ecule A, they are both on the same side of the mol-ecule whereas in mol-ecule B, one di-ethyl-fluorene moiety has undergone a 180° rotation such that the two pairs of ethyl residues appear on opposite sides of the mol-ecule. The fluorene ring systems subtend dihedral angles of 31.37 (4) and 43.18 (3)° in mol-ecules A and B, respectively. Hence the two fluorene moieties are tilted slightly toward one another. This may be due to the presence of inter-molecular C-H⋯π inter-actions between neighboring mol-ecules. The lateral ethyl chains (excluding H atoms) are also almost planar, with each pair almost perpendicular to the plane of the fluorene system to which they are attached with dihedral angles between the ethyl and fluorene planes in the range 86.04 (8)-89.5 (1)°.

Rational Design of Bay-Annulated Indigo (BAI)-Based Oligomers for Bulk Heterojunction Organic Solar Cells: A Density Functional Theory (DFT) Study.

Project description:In this paper, we have designed a series of oligomers based on the donor-acceptor concept. Here, acceptor bay-annulated indigo (BAI) dye and donor N-methyl-4,5-diazacarbazole (DAC) are joined by a thiophene linkage. We have substituted the 5th and 5'th positions of the acceptor unit and the 2nd position of the donor unit with various electron-withdrawing and electron-donating groups to study various structural and electronic properties of the compounds. In this regard, we have calculated the dihedral angle, distortion energy, bond length alteration (BLA) parameters, bang gap (Δ H - L ) values, partial density of states (PDOS), electrostatic potential (ESP) surface analysis, reorganization energy, charge transfer rates, hopping mobility values, and absorption spectra of the compounds. The ESP plots of the compounds indicate significant charge separation in the studied compounds. Our study manifests that the designed compounds are prone to facile charge transport.

9,9-Bis[4-(2-chloro-eth-oxy)phen-yl]-9H-fluorene.

Project description:The title compound, C(29)H(24)Cl(2)O(2), a fluorene derivative, features a C atom that is connected to four phenyl-ene rings, two of which are almost coplanar (r.m.s. deviation = 0.035 Å) as they belong to the fluorene system. The other two rings are aligned at angles of 67.5 (5) and 85.5 (5)° with respect to the pair. The O and Cl atoms of the -OCH(2)CH(2)Cl- units adopt a gauche conformation [torsion angles = 61.6 (6) and 66.6 (5)°].

Synthesis of 9,9-bis(4-hydroxyphenyl) fluorene catalyzed by bifunctional ionic liquids.

Project description:Through structural design, a series of bifunctional ionic liquids (BFILs) containing sulfonic acid (-SO3H) and sulfhydryl groups (-SH) were synthesized and characterized by NMR and MS. The acidity of these BFILs was measured by the Hammett acidity (H 0) and the effective sulfhydryl molar content of BFILs was determined by Ellman's method. Moreover, BFIL's catalytic properties in the condensation reaction of 9-fluorenone and phenol were studied. BFIL catalyst 6c can achieve nearly 100% conversion of 9-fluorenone with a high selectivity of 9,9-bis(4-hydroxyphenyl) fluorene (95.2%).

Solution-Crystallization and Related Phenomena in 9,9-Dialkyl-Fluorene Polymers. I. Crystalline Polymer-Solvent Compound Formation for Poly(9,9-dioctylfluorene).

Project description:Polymer-solvent compound formation, occurring via co-crystallization of polymer chains and selected small-molecular species, is demonstrated for the conjugated polymer poly(9,9-dioctylfluorene) (PFO) and a range of organic solvents. The resulting crystallization and gelation processes in PFO solutions are studied by differential scanning calorimetry, with X-ray diffraction providing additional information on the resulting microstructure. It is shown that PFO-solvent compounds comprise an ultra-regular molecular-level arrangement of the semiconducting polymer host and small-molecular solvent guest. Crystals form following adoption of the planar-zigzag ?-phase chain conformation, which, due to its geometry, creates periodic cavities that accommodate the ordered inclusion of solvent molecules of matching volume. The findings are formalized in terms of nonequilibrium temperature-composition phase diagrams. The potential applications of these compounds and the new functionalities that they might enable are also discussed. © 2015 The Authors.
