| Outline of Final Research Achievements |
Supramolecular organization between host and guest molecules utilizing the surface of metal nanomaterials is an interesting research topic in various fields such as optical,energy conversion, biological, and medical applications. Pentacene-alkanethiolate monolayer-protected gold nanoclusters (TP-Cn-X-MPC) and nanorods (TP-Cn-MPR) were successfully synthesized to examine the chain length (n =7, 11)-, structural size (X = S, L)- and surface shape- dependent structural and photophysical properties. The associate constants (Kapp) are largely dependent on the sizes of nanoclusters and alkyl chain lengths in TP-Cn-X-MPC (n =7, 11), whereas the Kapp values approximately remain constant in TP-Cn-MPR (n =7, 11). Efficient photocurrent generation was successfully observed on SnO2 films of pentacene and fullerene composites.
