    Investigation of the photoalignment effect of 1, 3, 4-oxadiazoles bearing 2-fluoro-4-methoxy phenyl moiety
    (2010) Alla, R.A.; Hegde, G.; Isloor, A.M.; Chandrakantha, B.; Shetty, P.; Komitov, L.
    A new series of 1,3,4-oxadiazole derivatives containing 2-fluoro-4-methoxy moiety were synthesized by refluxing mixture of acid hydrazide 3 with different aromatic carboxylic acid in phosphorous oxychloride. Photoalignment studies were performed on these materials indicating that the position of fluorine plays vital role in promoting planar alignment either parallel or perpendicular to the light polarization direction. � 2010 ITE and SID.

    Photoalignment of nematic liquid crystal by thin films of bishydrazones derived from 3,4 dipropyloxythiophene
    (2010) Alla, R.A.; Hegde, G.; Ravi, K.; Adhikari, A.V.; Vishnumurthy, K.A.; Komitov, L.
    Photoalignment of nematic liquid crystals (LC) promoted by thin films of bishydrazone derived from 3, 4 dipropyloxythiophene is studied. Experimental results show that bishydrazone without methyl group in their structure is promoting planar alignment parallel to the polarization direction of the actinic light whereas the ones with methyl group in the structure are promoting planar alignment perpendicular to light polarization direction. � 2010 ITE and SID.
