Functionalized porphyrin conjugate thin films deposited by matrix assisted pulsed laser evaporation

► We deposit 5-(4-carboxyphenyl)-10,15,20-tris(4-phenoxyphenyl)-porphyrin (CPPOPP) thin films by MAPLE. ► AFM investigations have shown that thin films have a quasi-continuous morphology dependent on incident laser fluence. ► Chemical structure of CPPOPP thin films is preserved for laser fluence values within the range 200-300 mJ/cm2. ► CPPOPP thin films are appropriate as a single mediator for glucose in the specific case of carbon paste screen-printed electrodes.
