| Research Abstract |
We have developed a variable-temperature single-molecule spectroscopy(SMS) apparatus and revealed photo physical/photochemical properties of several organic dyes and their nano-aggregates as follows. 1) The triplet lifetimes, intersystem crossing yields, and photobleaching yields for single-molecules of 9, 10-bis(phenylethynyl) anthracene embedded in polymer films were quantitatively determined. 2) We examined the electronic energy transfer(EET) in tetracence-doped p-terphenyl nanoparticles and theoretically revealed the origin of the extremely efficient EET in this system. 3) SMS of perylene bisimide(PDI) in aγ-cyclodextrin(γCD) solid film was performed, and we found that the hydrogen atom transfer reaction would take place between PDI andγCD in the inclusion complex.
