Influence of the properties of substituents in the para position (black arrows) of the azobenzene (A) on the position of the bands of both isomers in the visible range of the spectrum (B) and on the kinetics of photoisomerisation (k p, which is a function of molar attenuation coefficient ϵ and quantum yield φ) and thermal reisomerisation k t (C).
