摘要：

The chiroptical properties of two viscous chiral fluorophores, (R)-2,2'-hepthoxy-1,1'- binaphthyl [(R)-1] and its antipode [(S)- 1], dispersed in inorganic (KBr and KCl) and organic polymer ( PMMA and PS) matrices are studied in the photoexcited and ground states. Both (R)-1 and (S)-1 emit circularly polarised luminescence (CPL) with a high quantum efficiency in these solid matrices (15-58%) and in chloroform solution (14%).
