from the optically active binaphthyl moieties to the porphyrin chromophore at the molecular level. In particular, obvious bisignate Cotton effect is observed in the CD spectrum of the LB film of ( S )- 1 , revealing the right-handed chirality formed in the LB film. In addition, current–voltage ( I – V ) measurement result indicates good semiconductor feature of the LB film formed from ( S )- 1 with conductivity
带有四个手性联萘单元的旋光性无金属卟啉的(S)-对映异构体,即(S)-meso-5,10,15,20-tetra-[(11,12:13,14-di(6'设计,合成和表征了-辛基-1',2'-萘)-4,7,10,15,18,21-六氧杂环-苯基]-卟啉(1)。 )的(S)-1在氯仿溶液和LB膜中的光谱进行了表征,表明在分子水平上有效的手性信息从旋光联萘基转移到卟啉生色团。 (S)-1的LB膜的CD光谱,揭示了在LB膜中形成的右手性。 电流-电压(IV)测量结果表明,由(S)-1形成的LB膜具有良好的半导体特性,其电导率为1.22×10-5 S m-1。
