Method for controlling the emission lifetime of supramolecular illuminants

摘要

PROBLEM TO BE SOLVED: To provide a method capable of freely controlling especially luminous color and light emission lifetime in a solid luminescence material having excellent light emission property, and a luminophor capable of which luminous color and light emission lifetime can be controlled and which can be manufactured with simple operations.SOLUTION: There is provided a method for controlling luminous color and light emission lifetime of a supermolecule luminophor, the supermolecule luminophor is a packaged body of supermolecule constituted by a composite host formed by a B-N coordinate bond between Lewis acid consisting of tertiary boron compound and Lewis base consisting of an aromatic diimide compound and a gust molecule packaged by a cavity generated inside and outside of a structure of the composite host, the gust molecule is constituted by at least 2 kinds of molecules, at least one kind of the 2 kinds of molecules is a molecule containing a heavy atom, and luminous color and light emission lifetime of the supermolecule luminophor are controlled by properly changing kinds of the molecule containing the heavy atom and/or blended ratio in the gust molecule. There is also provided the supermolecule luminophor.SELECTED DRAWING: Figure 5
