The complete characterization of novel electropolymerizable organometallic complexes is presented. These are newly synthesized cyclometalated complexes of general formula (PPy)M(O (logical AND) N)(n) (H(PPy) = 2-phenylpyridine, M = Pd(II) or Pt(II), H(O (logical AND) N)(n) = Schiff base). Polymeric thin films have been obtained from these complexes by electropolymerization of the triphenylamino group grafted onto the H(O (logical AND) N)(n) ancillary ligand. The redox behavior and the photoconductivity of both of the monomers (PPy)M(O (logical AND) N)(n) and the electropolymerized species have been investigated. The polymeric films of (PPy)M(O (logical AND) N)(n) have shown a very significant enhancement of photoconductivity when compared to their monomeric amorphous counterparts. The high stability of the obtained films strongly suggests that electropolymerization of cyclometalated complexes represents a viable deposition technique of quality thin films with improved photoconduction properties, hence opening the door to a new class of materials with suitable properties for optoelectronic applications.[on SciFinder (R)]
