Compound: Tricyclohexylphosphonium tetrafluoroborate, is researched, Molecular C18H34BF4P, CAS is 58656-04-5, about Synthesis of regular D-A1-D-A2 copolymers via direct arylation polycondensation and application in solar cells. Author is Sun, Minmin; Wang, Wen; Lv, Wei; Lu, Mengxia; Yan, Shuhui; Liang, Luying; Ling, Qidan.
Two regular D-A1-D-A2 copolymers were synthesized via direct arylation polycondensation. In these copolymers, diketopyrrolopyrrole and benzothiadiazole were used as the acceptor units, while oligothiophene was used as the donor unit. Dodecyl group were also introduced into the thiophene moiety to explore the side chain effect on the properties of these copolymers. The optimum direct arylation reaction conditions were explored in order to obtain high mol. weight regular D-A1-D-A2 copolymer. It is found that the dodecyl group on thiophene moiety can improve the coplanarity and conjugation along the main chain of D-A1-D-A2 copolymer. These copolymers exhibit a broad absorption, narrow band gap and high packing order. Such properties are helpful for improving the photovoltaic properties. The relationship between the mol. weight and the photovoltaic property in copolymer P1 was also revealed. As the result, a higher power conversion efficiency of 3.65% was achieved for the copolymer P1 with a mol. weight of 86.1 kDa.
After consulting a lot of data, we found that this compound(58656-04-5)Formula: C18H34BF4P can be used in many types of reactions. And in most cases, this compound has more advantages.
