[摘要]：Sonogashira-Hagihara polycondensations of two bis(4-iodophenyl)carborane compounds with axially chiral diyne monomers having binaphthyl unit were carried Out to obtain the corresponding chiral pi-conjugated polymers having o- or m-carborane segment in the main chain. The polymer structures and their optical properties were characterized by H-1, C-13, and B-11 NMR, FT-IR, UV-vis absorption, photoluminescence, and circular dichroism spectroscopies. Photoluminescence study revealed that the polymer having m-carborane exhibited intense blue emission in Solution state, whereas polymers having o-carborane exhibited aggregation-induced emission (AIE). All polymers showed strong CD signals, indicating the construction of highly ordered conformation. |
