Classifications, properties, recent synthesis and applications of azo dyes.
TL;DR: This work has presented a very detailed review of the different classified azo dyes as a function of the number of azo groups and the appropriate functional groups and pointed out some chemical properties of these dyes such as reactivity, isomerization and tautomerism.

TL;DR: In this paper, two series of novel thermally stable second-order nonlinear optical and photochromic chromophores have been designed and synthesized, which act simultaneously as π-conjugated bridges, together with diazoaryl or diazothiazolyl as acceptor moieties.

Ab Initio Calculation of the Electronic Spectrum of Azobenzene Dyes and Its Impact on the Design of Optical Data Storage Materials
TL;DR: In this article, the second-order polarization propagator approximation (SOPPA) was used to calculate the excitation energies of 16 azobenzene dyes with different electron donor and acceptor groups and the correct shifts in excitation energy were obtained for the different substituents.

Thienylpyrrole azo dyes : Synthesis, solvatochromic and electrochemical properties
TL;DR: In this paper, the synthesis and evaluation of new donor-acceptor-substituted thienylpyrrole azo dyes are described, which exhibit dramatic changes in both their electronic and redox properties in comparison with traditional push-pull derivatives.

Negatively photochromic organic compounds: Exploring the dark side
TL;DR: A comprehensive review of negatively photochromic switches can be found in this paper, where the authors examine the dark side of photochromism, namely the ability of these molecules to undergo structural and electronic reorganisation which has been seized upon by materials scientists for the development of switches, logic gates, photoinduced molecular motions such as rotors and fibrils, and photoregulation of drug availability.
