Abstract
A novel porphyrin-(60)fullerene complex [bis(5,10,15,20-tetra-3-pyridinyl-21H, 23H-porphine)](60)-fullerene tetrahydrate, C60(Por)2·4H2O (1; Por = 5,10,15,20-tetra-3-pyridinyl-21H,23H-porphine) was synthesized via a hydrothermal reaction of 5,10,15,20-tetra-3-pyridinyl-21H,23H-porphine, C60, xylene and distilled water. The crystal structure is characterized by single-crystal X-ray diffraction. Compound 1 is characteristic of an isolated structure and each molecule contains two 5,10,15,20-tetra-3-pyridinyl-21H,23H-porphine moieties surrounding one C60 moiety, accompanied by four lattice water molecules. The porphine molecule features a saddle-distorted nonplanar macrocycle. The molecules in 1 are interconnected through van der Waals interactions to yield a supramolecular network. The photophysical properties of 1 in ethanol solution have been studied by photoluminescence and UV–Vis–NIR absorbance. A solution photoluminescence measurement shows that compound 1 can emit red photoluminescence with the maximum peak locating at 656 nm. Compound 1 has CIE (Commission Internationale de I'Éclairage) chromaticity coordinates of 0.70 and 0.30. The lifetime is 1.501 us and the quantum yield of 1 is 0.9%.
