摘要
We have investigated the electrical and optical properties of a water-soluble porphyrin monomer and its J-aggregate both in solution and in the solid state. Specifically, we find that water enhances the electrical conductivity, of both the monomer and the J-aggregate. The luminescence quantum efficiency and spectrum are also affected quite dramatically by the presence of water. The J-aggregate also shows an electrochromic effect in the presence of moisture. We show that the electrochromic effect arises because the J-aggregate converts to the monomer.
