제목 Self-assembly of Triphenylamine Derivatives in Several Non-chlorinated Organic Solvents with Additional Initiator
초록 Recently, Self-assembly behavior of triphenylamine (TPA) derivatives in chlorinated solvent with light has been reported. The key step of self-assembly is a generation of cation radical in TPA moiety which can be achieved by light in chlorinated solvent such as chloroform and dichloroethane. However, the light induced self-assembly system in chlorinated solvent must be protected from the ambient light exposure to prevent unwanted self-assembly and have limitation of its solvent system. Thus, finding a new self-assembly system allows extension of the self-assembly of triphenylamine derivatives in various organic solvents. We observed that TPA moiety could be oxidized in several non-chlorinated solvent with additional initiator such as Cerium (IV) + Methanol co initiator and N-bromosuccinimide (NBS). After oxidation of TPA derivatives, self-assembled structure (nano-rod) was generated.
