| Outline of Final Research Achievements |
Molecular design of a fluorescent probe responding to internal potentials, useful for innovative drug development against cancer, is discussed from the point of view of function of the crosslinked structure between fluorescent and response groups in the probe. It has been found that efficient photo-induced electron transfer occurs in the crosslinking of a short methylene chain and is inhibited by intermolecular electron transfer in the conjugated crosslinking. In addition, hydroquinone and catechol as well as ferrocene were found to be the good candidates for response groups to internal potential. On the other hand, o-carborane is likely to be the new fluorescent groups in the probes.
