Porphyrins are versatile chemical platforms owing to their metal-binding, catalytic, and supramolecular abilities underpinned by their strong absorption of light. Their photochemical applications in complex reaction media, however, are hampered by aggregation, as well as by difficulties in the synthesis and purification of functional derivatives. Here we present an efficient method for producing an A3B-type porphyrin platform in good yields from the readily available tetramethyl ester of meso-tetrakis-(4-carboxyphenyl) porphyrin (TCPP). This monovalent synthon can be easily functionalized and then grafted onto single-chain polymeric nanoparticles (SCPN) and 2D transition-metal dichalcogenides (TMD). We demonstrate the high utility of these hybrid materials by showcasing demanding photosensitization and photoelectrochemical applications.
