Abstract
RuL 2+3 (L=2,2′-bipyridine-4,4′-diphosphonic acid) thin solid films were fabricated by three-dimensional linking between the phosphonic acid substituents of L and Zr(O)Cl2. The RuL3 chromophores in the films are electronically independent of each other in the ground state and give emission spectra essentially identical to that of RuL 2+3 in solution, although the emission lifetime is much shorter. The films are electrochemically active, showing pseudo-reversible oxidation behavior in cyclic voltammetry. A preliminary attempt has been made to apply these films to photoelectrochemical cells.
