Sodium methylthiolate as an efficient deprotecting agent for dicobalt hexacarbonyl complexes of acetylenes

Various dicobalt hexacarbonyl acetylene complexes were efficiently converted to the unprotected acetylene by the reaction of two molar equivalents of sodium methylthiolate. Yields and reaction times depend upon the choice of solvent. DMF proved to be the

Double anchor indolo[3,2-: B] indole-derived metal-free dyes with extra electron donors as efficient sensitizers for dye-sensitized solar cells

Two new di-acceptors metal-free organic dyes based on indolo[3,2-b]indole donor backbone with extra electron donors were designed, synthesized, and applied for dye-sensitized solar cells (DSSCs). In this study, the effect of the additional donors was inve

Dicyanovinyl-substituted indolo[3,2-b] indole derivatives: Low-band-gap π-conjugated molecules for a single-component ambipolar organic field-effect transistor

A series of low-band-gap π-conjugated molecules comprising N,N′-dihexylindolo[3,2-b]indole as an electron donor (D) and dicyanovinyl as an electron acceptor (A) with A-π-D-π-A architecture have been designed and synthesized to fabricate a single-component

Solution processed bulk heterojunction solar cells based on A-D-A small molecules with a dihydroindoloindole (DINI) central donor and different acceptor end groups

Four acceptor-donor-acceptor (A-D-A) small molecules with dihydroindoloindole (DINI) as the central donor unit and different acceptor end groups such as dicyanovinylene (DCV), indenedione (IND), cyanoacrylate (CA) and rhodanine (Rho) linked through bithiophene as the π-linker, DINI-DCV, DINI-IND, DINI-CA and DINI-Rho, were designed and synthesized for the application as donor materials along with PC71BM as an acceptor for solution processed organic bulk heterojunction solar cells. The effect of acceptor end groups on the photovoltaic performance was investigated. The organic solar cells (OSCs) based on as cast DINI-IND showed the highest power conversion efficiency of 3.04%, as cast DINI-CA showed the lowest PCE of 1.63% and the other two exhibit a PCE in between them. These results showed that acceptor end groups affect the overall performance of the cells. The PCE of OSCs has been further improved up to 7.04% and 6.16% employing two-step annealing (TSA) treated DIN-IND:PC71BM (1:2) and DIN-CN:PC71BM (1:2), respectively. The enhancement in the PCE of OSCs with TSA treated active layers is attributed to the better nanophase morphology, the increase in the crystalline nature and light harvesting efficiency and more balanced charge transport and charge collection probability.
