摘要

Polymer(I)and polymer(Ⅱ) were obtained by the polymerization of (R)-6

6'-dibromo-2

2'-binaphtho-20-crown-6(M-1) and (R)-6

6'-dibromo-2

2'-di(methoxyethoxymethyloxy)-1

1'-binaphthyl (M-2) with p-divinylbenzene under Pd-catalyzed Heck reaction. The UV

fluorescence and CD spectra of polymer(I) and(Ⅱ) are similar due to the same linkers present in their polymer chain. Polymers (I) and(Ⅱ) can emit strong blue fluorescence and are expected to have potential applications in polarized blue-light emitting sensors. The chiral conjugated polymers (I) and(Ⅱ) exhibit a strong Cotton effect in their circular dichroism (CD) spectra

indicating a high rigidity of polymer backbone.
