摘要: | A new class of dicyanoboron diketonates (B(CN)2) was synthesized and the photophysical properties were investigated. The B(CN)2 complexes exhibited high molar absorption coefficients, large Stokes shifts, high photostability and low cytotoxicity. Especially, the emission of the B(CN)2 extended into the deep red region. The extensive p conjugation and the presence of intramolecular charge transfer (ICT) transitions are responsible for their red-shifted emission. Their fluorescence are very sensit |
