The photophysics and photochemistry of a series of naphthoxazinones have been studied using a combination of methods ranging from steady-state and time-resolved spectroscopic techniques to product analysis. The photophysics of naphthoxazinone derivatives is very dependent on the structure: phenanthrene-like compounds exhibit higher fluorescence quantum yield than the less aromatic anthracene-li...

A new anthracene-based X-shaped conjugated molecule, HBTATHT, was synthesized. Thin film transistors based on unannealed HBTATHT showed a carrier mobility of 0.15 cm(2) V(-1) s(-1) (I(on/off) = 7.9 × 10(6)). Further, a solution processed solar cell made of HBTATHT exhibited promising power conversion efficiencies of 4.84% and 4.70% with PC(61)BM (1:0.8 wt ratio) and PC(71)BM (1:0.6 wt ratio), r...

In this paper, we developed a new method to produce large-area single crystal arrays by using the organic semiconductor 9, 10-bis (phenylethynyl) anthracene (BPEA). This method involves an easy operation, is efficient, meets the demands of being low-cost and is independent of the substrate for large-area arrays fabrication. Based on these single crystal arrays, the organic field effect transist...

We report a molecular engineering study on optical, structural and electrical properties of seven silole derivates aiming at enhancing the balance of charge carrier in single-layer devices. By functionalizing two hole-transporting groups, dipyridylamine or anthracene, on the silole ring, we have investigated the influence of both entity types on the hole current. We have concluded that in contr...

The synthesis of one-dimensional tubular polymers via a preorganization-polymerization approach is presented. Prior to polymerization, photo-reactive monomers self-assemble into one-dimensional tubular structures in aqueous medium. The supramolecular polymers are subsequently converted into covalent polymers by light-induced anthracene dimerization.

In the title mol-ecule, C(35)H(22)BrNO(2), the four-membered ring of the β-lactam unit is nearly planar [maximum deviation = 0.003 (3) Å] and makes dihedral angles of 87.07 (15), 59.80 (16) and 20.81 (19)°, respectively, with the xanthene system, the anthracene system and the bromo-substituted benzene ring. The mol-ecular conformation is stabilized by weak intra-molecular C-H⋯O and C-H⋯N hydrog...

A new method is presented, which makes it possible to partition molecular properties like multipole moments and polarizabilities, into atomic and interatomic contributions. The method requires a subdivision of the atomic basis set into occupied and virtual basis functions for each atom in the molecular system. The localization procedure is organized into a series of orthogonalizations of the or...

Scintillation properties of 14-phenyl-14H-dibenzo[a,j]xanthenes (called material A) is studied. Cyclohexan is used as a solvent, whilst Anthracene and Naphthalene are used as secondary solutes. The response of the scintillator to low energy Gamma-rays is detectable. Our study shows that the addition of material A (0.01 mol L ) to the solution of Anthracene-Naphthalene-Cyclohexan, improves the d...
