Molecular sieves encapsulated organic dyes and metal chelates have been reviewed［1］,the luminescent behavior of some organic compounds in molecular sieves has also been studied［2,3］.Rh6G (Rhodamine 6G) is one kind of organic dye which is widely used in many fields such as optics,spectroscopy and laser techniques.It has a high stability and an efficiency quantum yield as an excellent fluorescent compound.The mesoporous molecular sieve MCM-41 possesses advantageous absorption property.It is conceivable that studies on the encapsulation of the fluorescent organic compounds in MCM-41 may give a new impetus to working on solid-state luminescence.We have reported the encapsulation of rhodamine B into MCM-41 and its fluorescent property［4］.In this paper,the encapsulation and the fluorescence of the functional supramolecular material of MCM-41,which was synthesized by means of MRM(Microwave radiation method),encapsulated Rh6G have been reported.
