5,7,12,14-Tetrafunctionalized 6,13-Diazapentacenes.

ABSTRACT: The synthesis, property evaluation, and single crystal X-ray structures of four 5,7,12,14-tetrafunctionalized diazapentacenes are presented. The synthesis of these compounds either starts from tetrabromo-N,N-dihydrodiazapentacene or from a diazapentacene tetraketone. Pd-catalyzed coupling or addition of a lithium acetylide gave the precursors that furnish, after further redox reactions, the diazapentacenes as stable crystalline materials. The performance of the tetraphenyl-substituted compound as n-channel semiconductor was evaluated in organic field effect transistors.

Crystal structure of 5,7,12,14-tetra-hydro-5,14:7,12-bis-([1,2]benzeno)-penta-cene-6,13-dione.

Project description:The lattice of 5,7,12,14-tetra-hydro-5,14:7,12-bis-([1,2]benzeno)-penta-cene-6,13-dione, C34H20O2, at 173?K has triclinic (P-1) symmetry and crystallizes with four independent half-mol-ecules in the asymmetric unit. Each mol-ecule is generated from a C17H10O substructure through an inversion center at the centroid of the central quinone ring, generating a wide H-shaped mol-ecule, with a dihedral angle between the mean planes of the terminal benzene rings in each of the two symmetry-related pairs over the four mol-ecules of 68.6?(1) (A), 65.5?(4) (B), 62.3?(9) (C), and 65.8?(8)° (D), an average of 65.6?(1)°. This compound has applications in gas-separation membranes constructed from polymers of intrinsic microporosity (PIM). The title compound is a product of a double Diels-Alder reaction between anthracene and p-benzo-quinone followed by de-hydrogenation. It has also been characterized by cyclic voltammetry and rotating disc electrode polarography, FT-IR, high resolution mass spectrometry, elemental analysis, and 1H NMR.

Bis(dimethyl-ammonium) 3,3'-dicarb-oxy-5,5'-(5,7,12,14-tetra-oxo-6,13-diaza-tetra-cyclo-[6.6.2.0(4,16).0(11,15)]hexa-deca-1,3,8,10,15-penta-ene-6,13-di-yl)dibenzoate dihydrate.

Project description:The title compound, 2C(2)H(8)N(+)·C(30)H(12)N(2)O(12) (2-)·2H(2)O, comprises dimethyl-ammonium cations, 3,3'-dicarb-oxy-5,5'-(5,7,12,14-tetra-oxo-6,13-diaza-tetra-cyclo-[6.6.2.0(4,16).0(11,15)]hexa-deca-1,3,8,10,15-penta-ene-6,13-di-yl)dibenzoate dianions and water mol-ecules. The dianion is situated on a crystallographic inversion centre. Two very strong symmetry-restricted O⋯H⋯O hydrogen bonds are present which are situated about the crystallographic inversion centres. In one of these hydrogen bonds, the H atom is situated at its centre, while in the other one the H atom is disordered about its centre. Both H atoms are involved in the chain-like C(2) (2)(16) motif, and not in a more common motif R(2) (2)(8) that is composed of a pair of hydrogen carboxyl-ates with the H atoms situated about the centre between the pair of O atoms. In the crystal, inter-action of these hydrogen bonds results in formation of anionic layers of dianions parallel to (-111). The water mol-ecules donate their H atoms to one of two of the carboxyl-ate O atoms, forming strong hydrogen bonds. The dimethyl-ammonium donates a bifurcated hydrogen bond to an oxo group of the dianion, forming weak hydrogen bonds. All the hydrogen bonds form a three-dimensional hydrogen-bonded network.

[6,13-Bis(2,4-dichloro-benzo-yl)-5,7,12,14-tetra-methyl-dibenzo[b,i][1,4,8,11]tetra-aza-cyclo-tetra-decinato- ??N]nickel(II) acetone monosolvate.

Project description:In the title complex, [Ni(C??H??Cl?N?O?)]·C?H?O, two 2,4-dichloro-benzoyl groups are grafted onto the methine groups of the Ni(II) complex Ni(tmtaa) (H?tmtaa = 5,7,12,14-tetra-methyl-4,11-dihydro-dibenzo[b,i][1,4,8,11]tetra-aza-cyclo-tetra-decine). The complex has the shape of a saddle. The Ni atom is tetra-coordinated by the four N atoms of the macrocycle, forming a slightly tetra-hedrally distorted square-planar geometry. The metal is displaced by 0.0101?(8)?Å from the N? mean plane. The aromatic rings of the 2,4-dichloro-benzoyl groups form dihedral angles of 87.1?(2) and 82.1?(2)° with the N? mean plane.

Synthesis of 6,13-difluoropentacene.

Project description:6,13-Difluoropentacene was synthesized from 1,4-difluorobenzene. Friedel-Crafts annulation of the latter with phthalic anhydride and subsequent reduction of the anthraquinone gave 1,4-difluoroanthracene. After ortho-lithiation and reaction with phthalic anhydride a carboxylic acid was obtained whose Friedel-Crafts acylation and subsequent reductive removal of the oxygen-functionalities resulted in the formation of the target compound. The HOMO-LUMO gap of 6,13-difluoropentacene was determined via UV-vis spectroscopy and compared to other fluorinated pentacenes.

Excited-State Dynamics of 5,14- vs 6,13-Bis(trialkylsilylethynyl)-Substituted Pentacenes: Implications for Singlet Fission.

Project description:Singlet fission is a process in conjugated organic materials that has the potential to considerably improve the performance of devices in many applications, including solar energy conversion. In any application involving singlet fission, efficient triplet harvesting is essential. At present, not much is known about molecular packing arrangements detrimental to singlet fission. In this work, we report a molecular packing arrangement in crystalline films of 5,14-bis(triisopropylsilylethynyl)-substituted pentacene, specifically a local (pairwise) packing arrangement, responsible for complete quenching of triplet pairs generated via singlet fission. We first demonstrate that the energetic condition necessary for singlet fission is satisfied in amorphous films of the 5,14-substituted pentacene derivative. However, while triplet pairs form highly efficiently in the amorphous films, only a modest yield of independent triplets is observed. In crystalline films, triplet pairs also form highly efficiently, although independent triplets are not observed because triplet pairs decay rapidly and are quenched completely. We assign the quenching to a rapid nonadiabatic transition directly to the ground state. Detrimental quenching is observed in crystalline films of two additional 5,14-bis(trialkylsilylethynyl)-substituted pentacenes with either ethyl or isobutyl substituents. Developing a better understanding of the losses identified in this work, and associated molecular packing, may benefit overcoming losses in solids of other singlet fission materials.

Dichlorido[(4E,11E)-5,7,12,14-tetra-benzyl-7,14-dimethyl-1,4,8,11-tetra-aza-cyclo-tetra-deca-4,11-diene]cobalt(III) perchlorate.

Project description:The Co(III) atom in the title complex, [CoCl(2)(C(40)H(48)N(4))]ClO(4), is octa-hedrally coordinated within a trans-Cl(2)N(4) donor set provided by the tetra-dentate macrocylic ligand and two chloride ions. The N-H atoms, which are orientated to one side of the N(4) plane, form hydrogen bonds with chloride ions and perchlorate-O atoms. These along with C-H?O inter-actions consolidate the three-dimensional crystal structure. One of the benzene rings was disordered. This was resolved over two positions with the major component of the disorder having a site-occupancy factor of 0.672?(4).

[(4E,11E)-5,7,12,14-Tetra-benzyl-7,14-dimethyl-1,4,8,11-tetra-aza-cyclo-tetra-deca-4,11-diene]copper(II) bis(per-chlorate).

Project description:The complete cation in the title compound, [Cu(C(40)H(48)N(4))](ClO(4))(2), is generated by the operation of a crystallographic centre of inversion. The Cu(II) ion exists in a tetra-gonally distorted trans-N(4)O(2) coordination geometry defined by the four N atoms of the macrocyclic ligand and two weakly bound perchlorate-O atoms from two anions. The N-H atoms form intra-molecular N-H⋯O(perchlorate) hydrogen bonds. Disorder was resolved in the -CH(2)-NH- portion of the macrocycle with the major component having a site-occupancy factor of 0.570 (6).

High-Resolution Electronic Excitation and Emission Spectra of Pentacene and 6,13-Diazapentacene Monomers and Weakly Bound Dimers by Matrix-Isolation Spectroscopy.

Project description:N-Heteropolycycles are among the most promising candidates for applications in organic devices. For this purpose, a profound understanding of the low-energy electronic absorbance and emission characteristics is of crucial importance. Herein, we report high-resolution absorbance and fluorescence spectra of pentacene (PEN) and 6,13-diazapentacene (DAP) in solid neon obtained using the matrix-isolation technique. Accompanying DFT calculations allow the assignment of specific vibrationally resolved signals to corresponding modes. Furthermore, we present for the first time evidence for the formation of van der Waals dimers of both substances. These dimers exhibit significantly different optical characteristics resulting from the change of electronic properties evoked by the incorporation of sp2 nitrogen into the molecular backbone.

Crystal structure of 15-(naphthalen-1-yl)-7,7a,8,9,10,11-hexa-hydro-6a,12a-(methano-epoxy-methano)-indolizino[2,3-c]quinoline-6,13(5H)-dione.

Project description:In the title compound, C27H24N2O3, the dihedral angle between the mean planes of the di-hydro-furan and 3,4-di-hydro-quinoline ring systems is 70.65 (9)°. The di-hydro-furan ring adopts an envelope conformation with the C atom adjacent to the methyl-ene C atom of the pyrrolidine ring as the flap. The five-membered pyrrolidine ring adopts a twist conformation on the N-C(tetra-substituted) bond. In the crystal, mol-ecules are linked via pairs of N-H⋯O hydrogen bonds, forming inversion dimers with an R 2 (2)(8) ring motif. The dimers are linked via pairs of C-H⋯O hydrogen bonds, forming ribbons enclosing R 2 (2)(12) ring motifs lying in a plane parallel to (01-1).
