Structural Assessment and Catalytic Consequences of the Oxygen Coordination Environment in Grafted Ti—Calixarenes.

Calixarene-Ti complexes were grafted onto SiO (0.18-0.24 Ti nm) to form isolated and accessible Ti centers persistently coordinated to multidentate calixarene ligands. Grafted Ti-tert-butylcalix-[4]arenes gave Ti K-edge absorption spectra with pre-edge features at 4968.6-4968.9 eV, independently of...
