英文摘要	Two well-defined triphenylamine-based fluorescent conjugated copolymers with pendant terpyridyl ligands were synthesized through suzuki coupling polymerization and were further characterized by (1)h-nmr, (13)c-nmr, gel permeation chromatography, infrared, and uv-vis spectra. polymer p-1, terpyridine-bearing poly(triphenylamine-alt-fluorene) with a high fluorescence quantum yield (62%) shows much higher sensitivities toward fe(3+), ni(2+), and cu(2+) as compared with the other metal ions investigated. especially, fe(3+) can lead to an almost complete fluorescence quenching of polymer p-1. whereas, the analogous polymer p-2, in which n-ethylcarbazole repeat units replace the fluorene units in p-1, shows a very poor selectivity. it demonstrates that polymers with a same receptor may show different sensitivity to analytes owing to their different type of backbones.
