Contribution of Diffuse Reflectance Spectroscopy to Monitoring the Synthesis Improvement of Encapsulated Complexes

摘要

Diffuse reflectance spectroscopy (DRS) can be regarded as a solid state technique contribution to monitoring the process of encapsulation of transition metal complexes into cavities of zeolites.By employing DRS,it was revealed that the effectiveness of a method suggested for higher encapsulation of a tris(bipyri-dine)cobalt(II) complex into zeolite Y can easily be manifested.In addition to that,simple diffuse reflectance spectra give information about a relative amount of two spin states of the cobalt bipyridine complexes and their alteration upon the method used.
