A class of potential luminescent sensing materials has been gradually developed in the form of luminescent metal–organic frameworks (LMOFs). A new LMOF with the formula {[Cd(BBZB)(bptc)0.5]·2H2O}n (JXUST-33, BBZB = 4,7-bis(1H-benzimidazole-1-yl)-2,1,3-benzothiadiazole, H4bptc = biphenyl-3,3′,5,5′-tetracarboxylic acid) has been successfully constructed, which exhibits the stability of structure and effectiveness of luminescence. Single-crystal X-ray diffraction studies have shown that two adjacent CdII ions are linked by a bptc4– ligand in different directions to form a plane that is further linked by interlaced BBZB ligands to form a three-dimensional two-fold interpenetrating framework. JXUST-33 can be used as a fluorescent probe to identify various organic molecules and detect three different organic compounds by the fluorescence quenching behavior of its luminescence properties. In addition, mixed substrate films based on JXUST-33 have been developed to achieve detection of acac, SA, and BZ via the naked eye, which has great potential for practical applications.

稳定的基于 CdII 的金属有机框架作为乙酰丙酮、水杨醛和苯甲醛的多响应发光传感器，具有高灵敏度和选择性
一类潜在的发光传感材料以发光金属有机框架（LMOF）的形式逐渐开发出来。一种新的LMOF，其分子式为{[Cd(BBZB)(bptc) 0.5 ]·2H 2 O} n ( JXUST-33 , BBZB = 4,7-bis(1 H -benzimidilla-1-yl)-2,1, 3-苯并噻二唑（H 4 bptc =联苯-3,3',5,5'-四羧酸）已成功构建，表现出结构的稳定性和发光的有效性。单晶 X 射线衍射研究表明，两个相邻的 Cd II离子通过 bptc 4–连接配体在不同方向上形成一个平面，该平面进一步由交错的BBZB配体连接，形成三维二维互穿框架。JXUST-33可作为荧光探针来识别各种有机分子，并通过其发光特性的荧光猝灭行为来检测三种不同的有机化合物。此外，基于JXUST-33的混合基底膜已被开发出来，可以实现肉眼检测acac、SA和BZ，具有巨大的实际应用潜力。
