- W1995342457 abstract "The optically active homopolymers polyl, polyll, and polylll and copolymers of 9-vinyl carbazole with (−)menthyl vinyl ether all exhibit fluorescence related to that of cationically and free radically prepared poly(9-vinyl carbazole). The fluorescence is interpreted for all polymers as arising from three components: monomeric carbazole emission, high energy excimer emission (termed dimer emission for convenience), and a more usual excimer emission arising from conformationally eclipsed carbazole units. Correlations of fluorescence and fluorescence quenching by maleic anhydride, with chiroptical properties and copolymer compositions, suggest that excimer formation is a consequence of rotational freedom within or between isotactic carbazole sequences in the polymer backbones. The isotactic copolymers of (−)menthyl vinyl ether and 9-vinyl carbazole exhibit a relatively strong excimer fluorescence even though mean sequence lengths of carbazole units are comparatively short." @default.
