2,6-Dicyanoaniline based donor-acceptor compounds: The facile synthesis of fluorescent 3,5-diaryl/hetaryl-2,6-dicyanoanilines

Abstract

A series of new 3,5-diaryl/hetaryl-2,6-dicyanoaniline derivatives were synthesized by three-component one-pot procedure at room temperature to 80°C. The experimental procedure in the preparation of the target compounds is simple, reproducible and it includes short reaction times and easy-isolation/purification of the products. The synthesized compounds are fluorescent active and show wavelength of maximum absorption (λ max) in UV or visible region in DMSO at room temperature.
