Due to the direct π - π interaction and excessive energy resonance transfer, it is very challenging to prepare CDs with high fluorescence quantum yield (QY) in solid state. In...
Fluorene-based molecules present significant nonlinear optical responses, multiphoton absorption in the visible, which, combined with the high fluorescence quantum yield in organic solvents, could make this class of materials potentially...
An ionic AIEgen with high fluorescence quantum yield shows remarkable and reversible mechanochromism as well as excellent mitochondrial imaging of cancer cells and long-term tracking of tumors.
By crooking conventional donor segments via suitable steric hindrance, nearly planar geometries, a small singlet–triplet energy splitting and a high fluorescence quantum yield can be realized simultaneously.
