3-(10-Alkyl-10H-phenothiazin-3-yl)-2-propenals and their corresponding 3,3′-bispropenals that represent a previously unexplored class of functionalised phenothiazine derivatives were prepared upon reacting N-alkylated 3-bromo- and 3,7-dibromo-10H-phenothiazines with acrolein diethyl acetal under Pd catalysis. The obtained heterocyclic 2,3-unsaturated aldehydes were condensed with N-methyl-N-phenylhydrazine and N,N-diphenylhydrazine resulting in mono- and dihydrazones that act as effective hole transporting materials. Thermal, optical, electrochemical and photophysical properties of the synthesised new organic electroactive derivatives have been investigated.

Abstract Conjugated polymers bearing pendant bipyridine groups, PM1PT-x, were synthesized in high yield from a carefully designed dibromocarbazole monomer M1 using a Suzuki coupling reaction with a phenothiazine diborate monomer. PM1PT-x, where x is the mole percentage of M1 in the total feed of dibromo-monomers and varied to levels of 25%, 50%, 75% and 100%, was reacted with a ruthenium complex to yield conjugated polymers bearing pendant bipyridine ruthenium complexes, PM1PT-x-Ru. The introduction of ruthenium complexes extended the absorption of PM1PT-x-Ru to the visible light region. Furthermore, these polymers demonstrated sufficient stability and suitable energy levels to potentially be highly efficient photoactive materials for polymeric solar cells.

A series of new push-pull phenothiazine-based dyes (HL1-HL4) featuring various π spacers (thiophene, 3-hexylthiophene, 4-hexyl-2,2-bithiophene) and double acceptors/anchors have been synthesized, characterized, and used as sensitizers for dye-sensitized solar cells (DSSCs). Among them, the best conversion efficiency (7.31 %) reaches approximately 99 % of the N719-based (7.38 %) DSSCs fabricated and measured under similar conditions. The dyes with two anchors have more efficient interfacial charge generation and transport compared with their congeners with only single anchor. Incorporation of hexyl chains into the π-conjugated spacer of these double-anchoring dyes can efficiently suppress dye aggregation and reduce charge recombination. Copyright

We present the synthesis and characterization of seven new organic co-poly-ynes P1-P7 incorporating the phenothiazine (PTZ) motif and evaluate their optoelectronic properties and performance in polymer light-emitting diodes and polymer solar cells (PLEDs/PSCs). The co-poly-ynes were obtained in moderate to high yields via Sonogashira coupling reactions and characterized using analytical, spectroscopic and electrochemical techniques and complementary quantum-chemical modelling. The materials show strong optical absorption in the visible region of the spectrum and most also show strong emission with quantum yields in the range of 13-41% relative to rhodamine 6G (R6G). PLED devices based on the co-poly-ynes were prepared and the most promising was measured to have a brightness of up to 1.10 × 104 cd m-2. PSCs based on donor materials incorporating some of the polymers were prepared and demonstrated power conversion efficiencies of up to 0.24%. This journal is

Provided are a novel thiophene derivative, a method for preparing the same, and an organic solar cell comprising the novel thiophene derivative. According to the present invention, the novel thiophene derivative that has a small band gap is prepared by copolymerizing an electron acceptor block and an electron donor block each consisting of thiophene units and vinylene units, and thus a highly efficient solar cell can be manufactured from the novel thiophene derivative. Furthermore, according to the present invention, an organic solar cell manufactured from the novel thiophene derivative having a small band gap has an improved performance and increased solubility, and can effectively absorb solar light.COPYRIGHT KIPO 2015
