Abstract

A bipyridine-based ligand 1 bearing two amphiphilic side chains allowed for the formation of metal complexes Pt(1)Cl2 (2), [Pt(1) 2](BF4)2 (3), and [Pt(1)2][Pt(CN) 4] (4), which are capable of templating the sol-gel synthesis of mesostrucutred silica to give 2-MS, 3-MS and 4-MS, respectively, whose silicate channels are filled with the corresponding platinum complexes. In particular, silica composite 4-MS, upon spin-coating, gives a transparent film, which emits at 619 nm upon excitation at 495 nm, indicating that a weak Pt-Pt bond, formed between Pt(1)22+ and Pt(CN)42-via a metallophilic interaction, is successfully incorporated into the silicate nanochannels.
