Facile fabrication of a red AIE luminogen with simple structure and bright emissions for cell imaging

Fluorescence imaging in red region is of great interest in both practical applicantion and fundamental research. However, the complicated synthetic approaches and low emission efficiency of the fluorescence materials are still implement their bilolgical applications. Herein, a facile synthesis method for a red luminogen with aggregation-induced emission (AIE) is reported. The AIE probe possesses simple structure and high red brightness, favoring its applications toward in vitro and vivo imaging. This study offers an ideal architecture for the construction of red AIEgens with a simple structure.
