Turn-on circularly polarized luminescent (CPL) molecular system realized by thermo-driven Newman-Kwart rearrangement reaction from CPL-silent O- to CPL-active S-thiocarbamate groups at peripheral position of 1,1 '-binapthyl rings

摘要

Although chiral 1,1'-binaphthalene-2,2'-diyl-O,O-bis(N,N-dimethylthiocarbamate) (1) revealed no circularly polarized luminescence (CPL) signals, Newman-Kwart rearrangement of O-thiocarbamate groups at 1 yielded clear CPL signals from 1,1'-binaphthalene-2,2'-diyl-S,S-bis(N,N-dimethylthiocarbamate) (2), which acts as a CPL-gen molecule.
