제목 Synthesis of Advanced Polymer Semiconductor with Silicon in DPP-Copolymer
초록 We designed a new DPP-based donor−acceptor polymer semiconductor whose functionalized alkyl side chains can facilitate highly efficient mini-emulsion synthesis. DPP-TVT was selected as a reference polymer semiconductor, and its Si-analogue, SiDPP-TVT, in which the carbon atoms of the branched alkyl chains of DPP-TVT were replaced with silicon atoms, is newly synthesized. By substituting silicon at the branching position of the alkyl side chain, the volumetric portion of the alkyl side chain is expanded by increasing the C−Si−C bond angle and the Si−C bond length compared to the conventional C−C−C bond angle and C−C bond length. The extension of the alkyl side chain group could increase the solubility and hydrophobicity of the synthesized SiDPP-TVT, which enables better molecular affinity with ionic surfactant.
