| 摘 要： | The present paper deals with the polybinaphthyls of (R）-3,3‘-Diiodo-2,2‘-binaphtho-20-crown-6 with p-divinylbenzedne under Heck-coupling reaction condition.Both the monomers and the polymer were analyzed by NMR,FTIR,UV,CD,fluorescent spectroscopy,polarimetry,GPC and elemental analysis.The polymer can emit a strong blue fluorescence and is expected to have the potential application in the polarized bluelight emitting sensors.The chiral conjugated polymer exhibits a strong Cotton effect in its Circular Dichroism (CD-) spectrum,indicating the high rigidity of the polymer backbone.
