Аннотация
A pi-conjugated organogelator (1) was synthesized, and its gelation ability was checked. It was found that it is an excellent gelator for some organic solvents, such as dichloromethane, benzene, o-dichlorobenzene, and DMSO/water. It can self-assemble into 1-D nanofibers induced by hydrogen bonding and pi-pi interactions. Moreover, 1 could form a hybrid gel with C(60)COOH by hydrogen bonds in which 1 and C(60)COOH can act as an electron donor and acceptor, respectively. It was found that the active film from the hybrid 1-D self-assemblies of 1 and C(60)COOH showed remarkably higher photocurrent generation compared with that containing 1 and C(60) because of the construction of interdigitated and ordered assemblies of donors and acceptors.
