An exploration of solvatochromism using anthranilic acid-based azo dyes

Presenter(s)

Kloe Dahl, Ella Denno, Ayla Sorg, and Nolan Spanier

Abstract

Solvatochromism, the influence of solvent on UV-visible spectra, was explored using an array of highly colored azo compounds (substances containing a N–N double bond). Visible absorption spectra of azo compounds formed from anthranilic acid and naturally occurring phenols were dissolved three different solvent types: polar protic, polar aprotic, and non-polar to ascertain their effects in terms of "red" or "blue" shifting of the observed spectra.
