Phenothiazine (PTZ)-based materials have recently received considerable interest owing to their intriguing optoelectronic properties, low-cost, versatility of functionalization, and commercial availability.
Two kinds in a box: The electronic and optical properties of ZnO substituted with nitrogen fluorine are studied both experimentally theoretically. presence enhances the incorporation lattice. Co-substitution reduces band gap significantly increases dielectric constant. long-wavelength visible absorption N, F-ZnO is reflected its bright orange color (see picture). As service to our authors readers, this journal provides supporting information supplied by authors. Such materials peer reviewed...
Three compounds consisting of the electron-donating triphenylamine-phenothiazine conjugate backbone and each electron-withdrawing groups 3-ethylrhodanine, malononitrile 1,3-indandione have been synthesized used as donors in blends with [6,6]-phenyl-C70-butyric acid methyl ester (PC71BM) for organic solar cell devices. After improvements active layer structure by a selected donor-to-acceptor weight ratio two-step solvent thermal annealing, cells showed power conversion efficiency (PCE) values...
Two small molecules <bold>BYG-1</bold> and <bold>BYG-2</bold> with fluorene donor benzothiadiazole acceptor units connected to the terminal naphthamide group <italic>via</italic> ethyne linker were designed synthesized.
The design and synthesis of three star‐shaped nonfullerene (NFA) acceptors, TPA‐2T‐INCN, TPA‐2T‐BAB, TPA‐T‐INCN, based on a triphenylamine (TPA) core linked through π ‐conjugated thiophene (T) spacers to different terminal units (3‐oxo‐2,3‐dihydro‐1H‐inden‐1‐ylidene) malononitrile, INCN, 1,3‐dimethylbarbituric acid, BAB), are reported. These materials blended with the widely used poly(3‐hexylthiophene‐2,5‐diyl) (P3HT) donor polymer tested in flexible organic photovoltaics (OPVs). NFAs capped...
