摘要： The present paper deals with the polymerization of (R)-3,3′-diiodo-2,2′-binaphtho-20-crown-6 with p-divinylbenzene 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 blue-light 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.
