PROCESS FOR THE PREPARATION OF BENZOHETERO [1,3] - DIAZOLE COMPOUNDS DISUBSTITUTED WITH HETEOARYL GROUPS

Process for the preparation of a benzohetero[1,3]diazole compound disubstituted with heteroaryl groups which comprises reacting at least one benzohetero[1,3]diazole compound disubstituted with at least one heteroaryl compound. Said benzohetero[1,3]diazole compound disubstituted with heteroaryl groups can be advantageously used in the construction of luminescent solar concentrators (LSC). Furthermore, said benzohetero[1,3]diazole compound disubstituted with heteroaryl groups can be advantageously used in the construction of photovoltaic devices such as, for example, photovoltaic cells, photovoltaic modules, solar cells, solar modules, on both a rigid and flexible support. Said benzohetero[1,3]diazole compound disubstituted with heteroaryl groups can also be advantageously used as a precursor of monomeric units in the preparation of semiconductor polymers.

Development of a new diindenopyrazine-benzotriazole copolymer for multifunctional application in organic field-effect transistors, polymer solar cells and light-emitting diodes

A new donor-acceptor (D-A) copolymer (PIPY-DTBTA) containing 6,12-dihydro-diindeno[1,2-b;1′,2′-e]pyrazine donor and benzotriazole acceptor was synthesized and characterized for multifunctional applications in organic field-effect transistors (OFETs), polymer solar cells (PSCs) and polymer light-emitting diodes (PLEDs). The polymer exhibits high molecular weights, excellent film-forming ability, a deep HOMO energy level, and good solution processability. Solution-processed thin film OFETs based on this polymer revealed good p-type characteristic with a high hole mobility up to 0.0521 cm2 V-1 s-1. Bulk-heterojunction PSCs comprising this polymer and PC61BM gave a power conversion efficiency (PCE) of 0.77%. The single-layer PLEDs based on PIPY-DTBTA emitted a yellow-red light with a maximum brightness of 385 cd m-2 at the turn-on voltage of 6 V.
