Synthesis of siloxane-integrated Schiff base compounds exhibiting aggregation-induced emission properties

Abstract

Schiff base compounds have garnered considerable research interest due to their promising fluorescence properties. In this work, we successfully synthesized two Schiff base compounds as aggregation-induced emission (AIE)-active luminescent agents using a simple and efficient one-step method. The molecular design of these compounds effectively combines the dual advantages of Schiff base structures and AIE effects, retaining the chemical stability and tunable optical properties of Schiff base compounds while exhibiting the unique AIE property of significantly enhanced fluorescence in the aggregated state. Owing to these AIE characteristics, the synthesized compounds show potential for application in biomedicine, including bioimaging, fluorescence sensing, and information security.
