Technology Lecture: Functional Organosilicas: Self-structuring Mechanisms; Photoluminescence; Functionalisation by 'Click' Chemistry

Date: 15 Mar 2011 - 15 Mar 2011

Venue: SIMTech Auditorium, Tower Block, Level 3

Introduction
This lecture provides an update on the new developments in the preparation methods and structure of functional materials that are of interest to the research community. The speaker represents a research group that is widely recognised as a leading research entity in France. It is widely recognised that there is a strong potential for eventual industry use for these methods in diverse areas from chemical synthesis to biomedical applications.

Abstract
'Bridged silsesquioxanes' are hybrid materials which are obtained by the hydrolysis of bridged organosilylated precursors. The introduction of urea groups in their structures can lead, depending on the hydrolytic conditions, to long-range ordered self-structured materials with a lamellar morphology. The possibility to obtain different morphologies and structuring degree from a single precursor following the sol-gel hydrolytic conditions will be discussed. The speaker will also discuss the formation of strongly luminescent hybrids containing or not lanthanide ions. The applications of the 'click' chemistry under anhydrous conditions at the level of the sol-gel precursors, or on silicas modified by 'clickable' functions will be introduced. It is widely recognised that there is a strong potential for eventual industry use for these methods in diverse areas from chemical synthesis to biomedical applications.

About the Speaker
Dr Xavier Cattoën is a researcher at the renowned Institut Charles Gerhardt Montpellier, France where he works on the development and use of effective chemical synthesis methods for the preparation of precursors that can be used in the formation of silica based nanoparticles. He also conducts experiments on nanoparticle preparation and characterisation.
