Effect of pH on Fluorescence Spectra of Coumarin Derivatives

Zain Ul Huda et al. J Fluoresc. 2022 Jan.

Abstract

Colourless crystalline solid coumarin with a bitter taste and sweet vanilla-like odor mostly acts as chemical protection against predators in plants. Anticoagulants (blood thinners), anti-fungicidal, anti-tumor and anti-inflammatory properties of coumarin are all used to treat skin diseases. Because of internal charge transfer (ICT), coumarin molecules displayed a solvatochromic effect in various solvents of varying polarity. The emission wavelength dependent fluorescence intensity was also affected by pH.

Keywords: Anticoagulants; Fluorescence; Internal charge transfer (ICT) and pH effect; Solvatochromic effect.
