INS study of solvatochromic effect induced by host-guest interactions in zeolites
The aim of this proposal is to understand the role of zeolite structure and the nature of extraframework cations (M=Li+, Na+, K+, Rb+, Cs+)on the solvent behavior of zeolites. The goal is planned to be achieved by a combined experimental and modelling study of salicylidenaniline molecule sorbed in cation-exchanged zeolites. The molecule, which is well known for its solvatochromic and photochromic properties, is expected to be a sensitive indicator of the details of host-guest interactions. Results of the study performed with a large palette of methods of electronic and vibrational spectroscopies and assisted by molecular modeling, will provide new data allowing a better understanding of reactivity of zeolites. The outcome of the project should provide a new insight on the acid-base characteristics of non-Brønsted acid zeolite and on the parameters controlling these characteristics.
