| Outline of Final Research Achievements |
The novel hybrid nanotubes (2-C60-PT-NT, Ag-C60-PT-NT, and Au-C60-PT-NT) involves the following new aspects: i) the template-based electropolymerization of 2-C60 produced the fullerene C60-polythiophene NTs (2-C60-PT-NT) which showed the reversible redox behaviour of the fullerene C60, and ii) the plasmonic hybrid NTs (Ag-C60-PT-NT and Au-C60-PT-NT) show a significant SERS compared to that of the NTs (2-C60-PT-NT) which were prepared from the template-based electropolymerization of 2-C60. It is worth pointing out that our approach to preparing a metal-polymer NT composite completely differs from all previous studies on the deposition of metal NPs onto the surface of polymer NTs. We observed a fluorescence enhancement and photostability for the polythiophene of the hybrid NTs (1-Ag-PT-NT) in solution, while no enhancement of the polythiophene fluorescence was observed in the mixture of the polythiophene NTs (1-PT-NT) and terthiophene-modified silver NPs (1-AgNP).
