摘要

The 1

1'-binaphthol based oligomers 3 and 7 with 3

3'-acetylene-phenylene-acetylene spacer were prepared fromBINOL 1. The high optical rotation value and CD spectra demonstrated the main chain chirality of the oligomer molecule.The UV-VIS and fluorescent spectra evidence the characteristics of conjugated structure. In comparison with oligomer 2bearing 3

3'-acetylene spacer

the oligomers 3 and 7 have longer efficient conjugation segment

and their fluorescent quantumyields (φ) increased (0.60-0.65 versus 0.14).Extending the effective conjugation segment would improve the photophysical properties of chiral conjugated polymers.
