文摘
The singlet excited state of the BZDs have a π-π* nature. A new dual fluorescence of BZDs f and g was observed. Intramolecular charge transfer (ICT) in the BZDs series proved by the solvatochromism, dual fluorescence, red shifts, larger Stokes shift. Compounds f and g had dual emission, stronger fluorescence intensity, and larger Stokes shift properties.
