Abstract
The syntheses and photochemical properties of the novel aminoaryldiarylboranes, 4, which are isoelectronic with triarylmethane dyes, and also pyrrolyl- 8, and indolyl-diarylboranes 11, are described. The fluorescence spectra are strongly dependent on the solvent. The use of o-disubstituted arenes as stabilizing substituents at the boron atom leads to highly coloured solids which are stable to air and moisture. The structures of the triarylboranes 4a and b were confirmed by X-ray analyses.Keywords
