Abstract

The synthesis and characterization of the first coordination polymer containing 1 as the linkers and titanium (IV) atoms as the nodes was investigated. Titanium (IV) isopropoxide was reacted with a dilute THF solution containing a stoichiometric amount of polyhedral oligomeric silsequioxanes (POSS). Even at elevated temperatures, 3 was sparingly soluble or insoluble in common organic solvents; therefore, most characterizations were performed using solid-state methods. Results of powder X-ray diffraction (XRD) and polarized optical microscopy of 3 were consistent with a crystalline solid. The solid-state 13C cross-polarization magic angle spinning (CPMAS) NMR spectra for both 1 and 3 were very similar, showing broad resonances from 133.3 to 127.2 ppm in each spectrum. A T3 type peak at -80.8 ppm corresponded to the four internal silicones in the POSS cage, each with three bridging oxygen and one phenyl substituent.
