Synthesis of a molecular tripod to anchor molecular coordination compounds to semiconductor nanoparticles

A 1,3,5,7-tetraphenyladamantane derivative having three arms terminating with carboxylic acids and a fourth substituted with a 9,10-phenanthrolinyl ligand was prepared as a new kind of molecular linkage to study dynamics of electron injection at the interface of TiO2 nanoparticles.
