Discrimination of dicarboxylic acids via assembly-induced emission

Abstract

Dicarboxylic acids are important chemicals in human metabolism and various industries. Differentiation between the isomers and members of a homologous series is a challenge, due to their similar properties. We show that a triazine-based fluorinated AIEgen can recognize dicarboxylic acids with selectivity based on the relative position of the two –COOH groups.
