Abstract:
A zinc-based pyrene-porphyrin hybrid linear 1-D coordination polymer ZnPyrPorp with general formula [Zn(Pyr)(Porp)] (Pyr = pyrene, Porp = tetraphenylporphyrin) was synthesized using a facile one-pot solvothermal method and fully characterized using different analytical techniques. The single-crystal X-ray diffraction (SCXRD) structure exhibited an interesting morphology with zinc metal coordinated to the porphyrin center, which was further bonded to the pyridine groups of the pyrene ligand, resulting in a linear 1-D-type polymer, with repeated Pyr-ZnTPP-Pyr units. The light-harvesting properties of the ZnPyrPorp polymer were investigated. Additionally, ZnPyrPorp showed excellent catalytic activity toward the photooxidation of 1,5-dihydroxynaphthalene.
