Controlling excited-state dynamics via protonation of naphthalene-based azo dyes† Azo dyes are a class of photoactive dyes that constitute a major focus of chemical research due to their applications in numerous industrial functions. This work explores the impact of protonation on the photophysics of four naphthalene-based azo dyes.

The doorstop proton: acid-controlled photoisomerization in pyridine-based azo dyes† Shea M. Martin, a Zachary J. Knepp, a Ing Angsara Thongchai, a Kiera Englehart,a Keyri Sorto,a Athina Jaffer,a Lisa A. Fredin *a and Elizabeth R. Young *a Abstract The photochemical properties and straightforward synthesis of a wide range of azo dyes has led to their use in a wide range of applications. Despite their broad use, the fundamental structure-function relationships of many variants are unexplored.

Ultra-fast excited-state dynamics of substituted trans-naphthalene azo moieties† Robert C. Hamburger, a Tao Huang,a Shea M. Martin, a Craig A. Pointer, a Lisa A. Fredin *a and Elizabeth R. Young *a Abstract In this work we untangle the ultrafast deactivation of high-energy excited states in four naphthalene-based azo dyes.
