Polybinaphthyls of (R)-3,3′-Diiodo-2,2′-binaphtho-20-crown-6 with p-Divinylbenzene via Heck Cross-coupling Reaction

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 an 1 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 eftect in its Circular Dichroism (CD-) spectrum, indicating the high rigidity of the polymer backbone.
