| Outline of Final Research Achievements |
In this research, a new strategy "Cyclic oligomerization method" for the construction of functional molecules applicable for the NIR laser dyes and bio-imaging probes was proposed and its effectiveness was demonstrated.
Complexation of novel multiply N-confused expanded calix[n]phyrins with boron difluoride afforded a new class of cyclic BODIPY (boron-dipyrromethene) arrays. The structures of circularly-arranged BODIPY subunits linked in an N-confused fashion give rise to such photophysical properties unique to the macrocycles as redshifted emission wavelengths along with apparent large Stokes shifts, long emission lifetimes and solid-state lasing. The DFT calculations support the size-dependent excited-state dynamics of the macrocycles.
