Abstract
The aim of this proposal is the investigation of microenvironments through the use of spectroscopic techniques, molecular modeling and simulation. Currently one of the most appealing fields in science involves the study of supramolecular factors, particularly the microenvironment, on the structure and reactivity of molecules. Such interest can be recognized in an expressive number of investigations on catalysts, blends, composite materials, modified electrodes, conducting polymers and interphases in general. Its main objective is the development and implementation of a methodology that involves the concerted use of vibrational spectroscopy and molecular modeling, thus allowing an unified approach to the microenvironment effects. Accordingly, the investigations will be performed mainly using vibrational spectroscopy to characterize the interphases and the microenvironment effects on molecular probes, as well as through molecular modeling and simulations in the case of simple systems or when a computational approach is feasible."spectroscopy, characterization and modeling of microenvironments" encompasses five sub-Projects, which are under the responsibility of researchers who constitute the Laboratory of Molecular Spectroscopy (LEM/IQUSP) and share the same facilities. The close scientific contact has led to several publications in common as a consequence of the affinity of their research interests, all centered in different aspects of vibrationaI spectroscopy. This proposal results from the maturing of projects currently under development in the Laboratory of Molecular Spectroscopy and from the realization of the benefits that an unifying approach based on the individual expertises would bring to the strengthening of the research group and to the training of quaIified human resources.
