Abstract

original image

The most highly charged water-soluble poly-ortho-substituted tetraarylporphycene (Pc8+) has been synthetized. The latter, which interacts in aqueous solutions with graphene oxide (GO) forming a photoactive ensemble Pc8+/GO, is immobilized by means of the Layer-by-Layer (LbL) technique onto ITO electrodes to afford novel solar energy conversion devices.
