Laser-induced graphene functionalized cationic porphyrin: fabrication, characterization, and intra-supramolecular electron transfer process.

We report herein a facile synthesis, characterization, and the electron transfer reaction of a novel light-harvesting material composed of laser-induced graphene (LIG) functionalized with the photoactive 5,10,15,20-tetrakis(4-trimethylammoniophenyl)porphyrin tetra(-toluenesulfonate) dye (TTMAPP). LIG was easily fabricated on the surface of a polyimide sheet using VersaLASER 3.6 (VLS 3.
