A red luminescent europium ion (Eu3+) doped CMP composite (Phen-Eu@BPPD-CMP) was prepared for the first time, in which Eu3+ ions coordinated with diketone moieties and 1,10-phenanthroline (Phen). The fluorescent composite could be used as a chemosensor for highly sensitive and selective detection of aluminum ions (Al3+). Compared to a linear polymer analogue (Phen-Eu@BPPD-LP), Eu3+-doped CMP without Phen groups (Eu@BPPD-CMP), and a Eu(OAc)3-BPPD-CMP mixture, Phen-Eu@BPPD-CMP allowed for the rapid detection of Al3+, which could have been caused by the mutual promotion of π-conjugated skeletons and the complementary coordination of Phen groups to facilitate the sensing process and improve the response to Al3+ ions.

红色发光的Eu3 +掺杂共轭微孔聚合物,用于铝离子的高灵敏度和选择性检测

首次制备了掺杂红色发光euro离子(Eu 3+)的CMP复合材料(Phen-Eu @ BPPD-CMP),其中Eu 3+离子与二酮部分和1,10-菲咯啉(Phen)配合。荧光复合材料可用作化学传感器,用于高度敏感和选择性地检测铝离子(Al 3+)。与线性聚合物类似物(Phen-Eu @ BPPD-LP)相比,Eu 3+掺杂的无Phen基团的CMP(Eu @ BPPD-CMP)和Eu(OAc)3 -BPPD-CMP的混合物Phen-Eu @ BPPD-CMP可以快速检测Al 3+,这可能是由于π共轭骨架的相互促进和Phen基团的互补配位,以促进传感过程并改善对Al 3+离子的响应所致。
