文摘

A π-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 π−π interactions. Moreover, 1 could form a hybrid gel with C₆₀COOH by hydrogen bonds in which 1 and C₆₀COOH 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 C₆₀COOH showed remarkably higher photocurrent generation compared with that containing 1 and C₆₀ because of the construction of interdigitated and ordered assemblies of donors and acceptors.
