Two zero-dimensional inorganic–organic hybrids, namely, [C₄mim][Cd(TCDPPA)₃] (1) and [C₄mpy][Cd(TCDPPA)₃] (2), where (TCDPPA)⁻ = 2,2,2-trichloro-N-(di(pyrrolidin-1-yl)phosphoryl)acetamide, (C₄mim)⁺ = 1-butyl-3-methylimidazolium, and (C₄mpy)⁺ = 1-butyl-4-methylpyridinium, have been synthesized via metathesis reactions and characterized systematically. These ionic cadmium-containing inorganic–organic hybrid compounds are assembled from a bulky organic cation and a complex anion constructed from the chelation of three TCDPPA ligands to one cadmium ion. These compounds possess wide band gaps and emit in the deep-blue region intensely with a quantum yield as high as 34.04%. The success of this work provides a new method for the design and fabrication of high-efficiency blue-emitting materials.

由β-二酮配体和大体积有机阳离子构成的蓝光零维无机-有机杂化物

两个零维无机-有机杂化物，即 [C ₄ mim][Cd(TCDPPA) ₃ ] ( 1 ) 和 [C ₄ mpy][Cd(TCDPPA) ₃ ] ( 2 )，其中 (TCDPPA) ⁻ = 2 ,2,2-三氯-N- (二(吡咯烷-1-基)磷酰基)乙酰胺，(C ₄ mim) ⁺ = 1-丁基-3-甲基咪唑，和(C ₄ mpy) ⁺= 1-butyl-4-methylpyridinium，已通过复分解反应合成并进行了系统表征。这些离子型含镉无机-有机杂化化合物由一个庞大的有机阳离子和一个复杂的阴离子组装而成，该阴离子由三个 TCDPPA 配体与一个镉离子螯合而成。这些化合物具有宽禁带，在深蓝色区域发光强烈，量子产率高达34.04%。该工作的成功为高效蓝光材料的设计和制备提供了一种新方法。
