Although there is much interest in the use of azobenzenes (ABs) as molecular switches for biological and material science applications, there is still need for systematic rationalization of their photophysical properties determined at both experimental and theoretical level. We present here the (re-) evaluation of the properties of some AB derivatives in the context of their geometrical substitution (para or meta) and nature of substituent effects (i.e. electron-donating groups, EDGs or electron-withdrawing groups, EWGs). Results of comprehensive experimental studies of their photophysical properties, thermal stabilities and functioning in reducing environments are rationalized by DFT calculations. As the associated n-pi* bands of the trans (E) and cis (Z) isomers of the studied ABs overlap, it is difficult to obtain high cis-to-trans conversion, however we have proved that by manipulation of the substituents position, the content of the cis isomer at the photostationary state (PSS) could be enhanced up to 30%. Moreover, we show that the presence of -NHCO- group at para positions contributes to reducing the effective bond order of the azo group resulting in the reduction of the height of the energy barrier for conversion and reduces the half-life of the cis isomer. Finally, electron deficient ABs are found to be more stable under reducing environments.
