a result of electron microscope analysis it can be shown that its particle size was reduced to at most 200 u02dc 500 nm fig7 a a porous organic inorganic hybrid material was prepared in the same method as example 4 except that the organic inorganic hybrid material was prepared by heating for 6 hours by an electric heating using the conventional electric heating instead of irradiating microwaves as a heat source as a result of xrd analysis it can be confirmed that relative intensity of the peak was different however a diffraction pattern was shown in the same position as example 4 as for the crystal structure of the organic inorganic hybrid material prepared as above as a result of analysis using an electron microscope a relatively large crystal whose particle size is 2 5 u03bcm was obtained an organic inorganic hybrid material was prepared in the same method as example 2 except that heating by microwaves irradiation was used instead of the electric heating in example 2 however the organic inorganic hybrid material was prepared by using microwaves reaction device of 2 5 ghz and maintaining the reaction temperature at 210 u00b0 c for 40 minutes the x ray diffraction pattern analysis showed that this material is having the same structure as in example 2 an organic inorganic hybrid.
