Behaviour of 4-(N,N-dimethylamino)benzonitrile in Molecular Solvents and Deep Eutectic Solvents

Abstract

Molecular solvents (MS) are extensively used in research and development industries. However, they have drawbacks, like toxicity, high volatility, and high polarity. Recently, green solvents have been found to be safer solvents. Deep eutectic solvents (DES) are green solvents that promise low volatility, non-toxic, non-hazardous, and biodegradable. However, these green solvents have relatively high viscosity. Thus, DMABN, a fluorescent probe, is used in studying the viscosities and polarity of DES and MS.
