| Outline of Final Research Achievements |
Hybrid films of functional molecules and metal nanoparticles have been considered to be novel photo-functional devices. We have successfully constructed hybrid films of silver nanoparticles and ruthenium polypyridine derivatives on substrates. In order to hybridise them on a surface, a self-assembled monolayer method via chemical bond formation and electro-reductive polymerisation via physical attachment have been employed. These methods have the advantage of convenient and reproductive fabrications of complicated hybrid films. Furthermore, it has been clarified that these hybrid films show unique photo-functional behaviours, such as enhanced photocurrent generation. On the other hand, photocurrent generation efficiency via the photoactive dyes, porphyrins, was strongly enhanced by construction of a nanocomposite structure. The photo-absorption of the porphyrin was significantly influenced by normal and gap-mode plasmon bands.
