Optical and physico-chemical properties of tetrapyrrole molecules in nanoporous silicate gel matrices

Abstract

In this mini-review, we present the main results of our works on the spectroscopy of the molecules of tetrapyrrole pigments incorporated into nanoporous gel matrices. Xerogels activated by organic dyes are promising materials for applications in various fields of technology. The influence of the technique of embedment of the activator molecules on their physico-chemical properties has been analyzed. The specificity of the action of a silicate matrix as external medium, as compared to liquid and solid solutions, is shown.
