• 1,6-di(N-methyl-pyridinium-3-yl)-pyrene(m-Py^<2+>) was synthesized. Photochemical properties were observed for m-Py^<2+> itself and m-Py^<2+>/clay complexes. Judging from Lambert-Beer plot analysis, m-Py^<2+> molecules adsorb on the clay surface without aggregation up to 60 % versus cation exchange capacity of the clay. m-Py^<2+> molecule emits fluorescence from excimer on the clay surface. An energy transfer reaction from excited singlet m-Py^<2+> to the ground-state p-TMPyP on the clay surface was examined. The maximum energy transfer efficiency was 13 %. These findings indicate that pyrene derivative is expected as energy donor which can absorb shorter wavelength light in the visible region towards the establishment of artificial light-harvesting system.
