“…The principal electronic absorption bands of the azomethine dyes exhibit a high degree of sensitivity to changes in the solvent environment and this characteristic of the dyes has provided one experimental route to the measurement of solvent polarity (1). Phenol Blue (or A'-(4-dimethylaminophenyi)benzoquinonemonoimine) has been the most thoroughly examined azomethine dye from both the experimental and theoretical viewpoints (2)(3)(4). The significant influences shown by minor structural changes in the dye molecule and by possible hydrogen bonding from the solvent led Figueras to conclude that solvent polarity scales based on solvatochromism can have only limited utility (3).…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
