Abstract
Three kinds of chiral BINOL-based polymers could be synthesized by polymerization in a Pd-catalyzed cross-coupling reaction. The resulting chiral polymers can exhibit strong mirror image Cotton effects. Interestingly, only P2 and P3 can emit circularly polarized luminescence (CPL) signals, which can be attributed to the chirality transfer of the BINOL moiety via the rigid π-conjugation chain backbone structure system. This work can develop a new strategy for the design of novel CPL materials.
