Synthesis of fluorescent alkoxybenzylidene derivatives of malononitrile dimer in water in the presence of Triton X-100

Abstract

An efficient procedure has been developed for the synthesis of alkoxybenzylidene derivatives of malononitrile dimer in water in the presence of nonionic surfactant (Triton X-100). Depending on the number and position of alkoxy groups, the products showed solid-state fluorescence with the emission maximum in the range λ 491–560 nm.
