Abstract
Four chiral conjugated polymer-1 (P-1), polymer-2 (P-2), polymer-3 (P-3) and polymer-4 (P-4) were obtained by the polymerization of (S)-6,6′-dibromo-2,2′-bisbutoxy-1,1′-binaphthyl ((S)-M-1) and (R)-6,6′-dibromo-2,2′-bisbutoxy-1,1′-binaphthyl ((R)-M-1) with 1,4-divinyl-2,5-dibutoxybenzene (M-2) and 1,3,4-oxadiazole-2,5-bis(4-vinylbenzene) (M-3) under Pd-catalyzed Heck reaction respectively. Both monomers (S)-M-1, (R)-M-1, M-2, M-3 and polymers were analyzed by NMR, MS, FT-IR, UV, fluorescent spectroscopy, polarimetry, GPC, circular dichroism (CD-) spectra. Four polymers can emit stronger green-blue fluorescence and are expected to have the potential application in the polarized light-emitting sensors.
