A Comparative Study Of D-C Electrochemiluminescence from Poly(2-methoxy-5-dodecyloxy-p-pheynylenevinylene) in Solution and in Solid Polymer Electrolyte Media

Abstract

D-C electrochemiluminescence (ECL) of poly(2-methoxy-5-dodecyloxy- p-pheynylenevinylene) was observed for the film immersed in an electrolytic solution and for its dry composite film with a solid polymer electrolyte using interdigitated gold electrodes spaced 5 µ m apart. The coincidence of the onset voltages and spectra of the ECL suggests that both ECLs can be interpreted by the same mechanism: negatively and positively charged excited species of the polymer are formed at the cathode and anode, respectively, and recombine between the electrodes to form singlet excitons which radiatively relax to the ground state.

“…Later examples have been reported using MEH-PPV ( 20 ), P3HT ( 647a ), or MDOPPV ( 1194 ) as films cast on the working electrode. ECL has also been observed from 1194 in solution and as a blend with PEO . Other examples in solution have also been reported. , The ECL spectra generally closely match the PL spectra.…”
