Outline of Final Research Achievements

Developing an active photocatalyst that efficiently uses the solar spectrum is a crucial issue to eliminate large amounts of polluting or undesired substances. In the present study, some types of organic p-n bilayers were prepared and applied to a photocatalytic reaction. In particular, an organo-bilayer, comprising n-type perylene derivative (PTCBI) and p-type lead phthalocyanine (PbPc), successfully worked as a photocatalyst responding to both visible-light and Near IR energy, which was superior to a reference system capable of photocatalysis under the full visible-light irradiation [i.e. the system composed of n-type PTCBI and p-type metal-free phthalocyanine (H2Pc)]. This work showed that the effective use of wide range in the solar spectrum is vital for driving a photocatalytic reaction.
