由1,9-二卤代联苯并吡咯与吡咯的直接Snar反应合成了一系列新的联苯并吡咯类化合物,它们在近红外波段(650-800 nm,以盐酸盐形式存在)有很强的吸收。1,9-二卤代联吡咯和吡咯上的取代基对反应的活性和产物的吸收性能都有很大的影响。这些二苯并吡咯类化合物对锌离子表现出灵敏和选择性的“开启”荧光响应。
A set of dipyrrolyldipyrrins have been efficiently synthesized from a direct SNAr reaction on 1,9-dihalodipyrrins with pyrroles and show intense absorption in the NIR region (650–800 nm, as HCl salts). Substituents on both 1,9-dihalodipyrrins and pyrroles greatly affected the reactivity of this SNAr reaction and the absorption properties of the resultant dipyrrolyldipyrrins. These dipyrrolyldipyrrins show sensitive and selective “turn-on” fluorescence response toward Zn2+.
