合成了一种简单的芴低聚物7，7′-双（9，9-双（6-（9 H-咔唑-9-基）己基）-9H-芴-2-基）-9，9，9 Mobi，9 ′-四（6-（9 H-咔唑-9-基）己基）-9H，9 ′H-2，2′-联芴（OCZ），并将其作为碘离子（I-）的比色/荧光探针。它对I-表现出高的荧光猝灭灵敏度和选择性。当OCZ作为比色探针时，在0.1mM的非常低的浓度下用肉眼观察到颜色变化，这是已报道的最好的性能之一。这种良好的灵敏度和选择性可能是由于富电子咔唑基团的广泛范围。
A simple fluorene oligomer 7, 7′-bis(9, 9-bis(6-(9H-carbazol-9-yl)hexyl)-9H-fluoren-2-yl)-9,9,9′,9′-tetrakis(6-(9H-carbazol-9-yl)hexyl)-9H, 9′H-2, 2′-bifluorene (OCZ) with peripheral carbazole side chains is synthesized and used to detect iodide (I−) as colorimetric/fluorometric probe. It shows high fluorescence quenching sensitivity and selectivity towards I−. When OCZ acted as the colorimetric probe, the color change is observed with naked eyes at a very low concentration of 0.1mM, which is among the best reported performances. The good sensitivity and selectivity may be due to the wide range of electron-rich carbazole groups.
