Abstract

The present proposal seeks to prepare new optical materials based on polynuclear copper (I) halide cluster complexes immobilized as guest molecules in solid host matrices. While the rich variety of their photophysical properties in the molecular state have been characterized in great detail in liquid solution their potential application as optical materials requires their incorporation into solid host matrices. To accomplish this goal, different immobilization strategies based on sol-gel co-assembly, design of core-shell systems, and other topotactical modification techniques will be pursued. Furthermore, the use of bidentate ligands (1,4-pyrazine, 4,4'bipyridine) offers the possibility of constructing 3D metal-organic frameworks MOF-s).The photophysical properties of the resulting materials will be characterized by ground and excited-state absorption, steady state and time-resolved emission and excitation, with a particular emphasis on temperature dependent studies. The functional characteristics of these materials will be correlated with detailed structural investigations using modern solid state nuclear magnetic resonance techniques as a probe of intermolecular guest-host and guest-guest interactions. Based on these studies we hope to understand and exploit rigidochromic mechanisms for tailoring the optical properties of tetranuclear copper(I) halide cluster complexes, towards desired applications. This project fits nicely into the scope of one of our research lines to be developed as part of CeRTEV - Center for Research, Technology and Education on Vitreous Materials.
