of N2O-type benzopyrromethene boron complexes
have been synthesized from the condensation of pyrrole, formylisoindole,
and various boronic acids. These dyes have red/near-infrared absorption,
high solution- and solid-state fluorescence, as well as good solubility
in a variety of solvents due to the presence of axial-substituted
groups that provide steric protection and prevent their possible aggregations.
Two water-soluble derivatives with pyridinium ions were developed
as near-infrared excitable mitochondrially localizing fluorescent
probes.
