This paper describes the synthesis of 4,4′-[(triisopropoxysilyl) propyloxy]azobenzene and the preparation of the ordered hybrid material containing the bridged azobenzene moieties within the framework by using the direct liquid crystal templating approach. We show that a sizable fraction of the azobenzene groups is reversibly photoisomerized though the chromophore is covalently linked to the silica matrix at both ends. In contrast, the photoisomerization did not occur in the corresponding material prepared in the absence of template. This is explained by a regular dilution of the chromophores into silica thanks to the template used for the preparation of the material. The Royal Society of Chemistry 2005.

Page/Page column 23, (2010/02/14)
Diol derived blocked mercaptofunctional silane compositions in which the silanes comprise cyclic and bridged alkoxy groups derived from hydrocarbon-based diols and processes for their preparation are provided. Also provided are rubber compositions comprising the cyclic diol-derived blocked mercaptofunctional silanes, processes for their preparation and articles of manufacture comprising the rubber compositions, in particular, automotive tires and components thereof.
