A new fluorescent chemosensor 2-(2-thiophene)imidazo [4,5,f]-1,10-phenanthroline (L) was prepared and characterized. By adding univalent or divalent metal ions such as Na(+), K(+), Mg(2+), Ba(2+), Mn(2+), Fe(2+), Co(2+), Ni(2+), Cu(2+), Ag(+), Zn(2+), Cd(2+) and Hg(2+) ions into the solution of L in DMF under buffered conditions with the working pH ranging from 7.0 to 8.0, we found that L could be used to detect K(+) ratiometricly and it could also be applied to sense Co(2+) with the phenomenon of fluorescence quenching of L. While the response behavior of L was not discernibly affected by other examined metal ions.
一种新的荧光化学传感器 2-(2-噻吩)咪唑并[4,5,f]-1,10-菲咯啉（L）被制备并进行了表征。通过向 L 在 DMF 中的溶液中加入单价或二价金属离子，如 Na(+)、K(+)、Mg(2+)、Ba(2+)、Mn(2+)、Fe(2+)、Co(2+)、Ni(2+)、Cu(2+)、Ag(+)、Zn(2+)、Cd(2+)和 Hg(2+)离子，在缓冲条件下，工作 pH 值范围为 7.0 至 8.0，我们发现 L 可以用于比率检测 K(+)，并且还可以用于检测 Co(2+)，L 的荧光猝灭现象。而 L 的响应行为不受其他检测金属离子的明显影响。
