New Para-substituted Non-symmetric Isoflavones for Their Fast Photo-switching Ability: Synthesis and Their Liquid Crystal Characterization
The first example of non-symmetric isoflavone-based fast photo-switchable liquid crystals with different functional groups at theterminalposition were synthesized and characterized. Polarizing optical microscopy study revealed that the compounds showed least ordered nematic phase. Optical photo swi...

| description | The first example of non-symmetric isoflavone-based fast photo-switchable liquid crystals with different
functional groups at theterminalposition were synthesized and characterized. Polarizing optical microscopy study revealed that the compounds showed least ordered nematic phase. Optical photo switching study exhibited very fast photoisomerization effect in solution. TheE–ZandZ–Econversion occurred around 3–5 s and 40–700 s respectively. This is also the first example ofpara-substituted non-symmetric isoflavone liquid crystals exhibiting very fast photo switching property in solution. Argument based on non-symmetrical behaviour might be the reason for the observed behaviour. |
