A family of six 8-amino boron dipyrromethenes having Formulas 1, 2, 3, 4, 6, and 7 has been prepared. The presence of the amine group alters the emission properties of the boron dipyrromethene, such that these compounds are characterized by unexpected blue fluorescence, providing for potential use as lasers. The compound having formula 1 has very high quantum yield. The 8-amino boron dipyrromethenes are prepared in a straightforward, high yield synthesis by substituting an amine group for the thiomethyl group at the 8 position in 8-thiomethyl boron dipyrromethene. The compounds having Formulas 6 and 7 may be used to incorporate peptides and proteins, thus providing biomolecules marked with fluorescent fragments.
