A microporous metal–organic framework (MOF) Eu3(MFDA)4(NO3)(DMF)3 (1, H2MFDA = 9,9-dimethylfluorene-2,7-dicarboxylic acid) has been solvothermally synthesized and structurally characterized by single-crystal X-ray diffraction. 1 is a three-dimensional coordination polymer with pcu type rod-packing structure, through which 1D rhombic channels penetrate. The solvent-free form 1a could be obtained by direct heating of 1. Both 1 and 1a exhibit high intensity red light emissions with high quantum yields and long luminescence lifetimes when excited at 336 nm at ambient temperature. The potential of 1a for nitro explosive sensing is studied through luminescence quenching experiments, which show that 1a is a potential luminescent sensory material for nitro explosives.
一种微孔金属-有机骨架(Eu3(MFDA)4(NO3)(DMF)3，1，H2MFDA = 9,9-二甲基芴-2,7-二羧酸)已通过溶剂热合成法合成，并通过单晶 X 射线衍射进行了结构表征。1 是一种具有 pcu 型棒状堆积结构的三维配位聚合物，其中贯穿有 1D 菱形通道。通过直接加热 1 可以得到无溶剂形式的 1a。在室温下，当用 336nm 激发时，1 和 1a 都表现出高强度的红光发射，具有高量子产率和长荧光寿命。通过荧光猝灭实验研究了 1a 对硝基爆炸物的传感潜力，结果表明 1a 是一种潜在的用于检测硝基爆炸物的发光传感材料。
