    • Compounds related to those object of this study, with appropriate substituent groups, owing to their photochemical stability, are widely employed as dyes Commercial names are, for example, Bismarck Brown R and Sudan 403. To the best of our knowledge, no information is available on photoreactive conjugated bis(azo) compounds.

    • Unfortunately, the pitches of the cholesteric phases obtained by doping the compounds (E,E)-p-1 and (E,E)-m-1 in several nematic phases do not change to an appreciable extent during the photoisomerisation process. Furthermore, the circular dichroism spectroscopy in ordinary solutions does not give any evidence of formation of skewed, helicoidal conformations of the solute molecules [O. Pandoli, Laurea Thesis, University of Bologna (Italy), 2003]. For a recent successful bis(azo) chiral photochemical switch for liquid crystal doping, see: S. Pieraccini, S. Masiero, G. P. Spada, G. Gottarelli, Chem. Commun. 2003, 598.
