AI Article Synopsis
Two new inorganic-organic hybrid compounds have been synthesized, identified as [Cmim][Cd(TCDPPA)] and [Cmpy][Cd(TCDPPA)], which incorporate a cadmium ion and complex organic ligands.
These hybrids are constructed from a bulky organic cation and feature a complex anion formed by three TCDPPA ligands binding to a single cadmium ion.
They demonstrate significant deep-blue light emission with a high quantum yield of 34.04%, offering a promising approach for creating efficient blue-emitting materials.
Article Abstract
Two zero-dimensional inorganic-organic hybrids, namely, [Cmim][Cd(TCDPPA)] () and [Cmpy][Cd(TCDPPA)] (), where (TCDPPA) = 2,2,2-trichloro--(di(pyrrolidin-1-yl)phosphoryl)acetamide, (Cmim) = 1-butyl-3-methylimidazolium, and (Cmpy) = 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.
