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。
