The target molecule namely the 1,4-bis[4-(4-acetylphenylazo) phenoxy] butane is obtained and the mesomorphic properties of the compound is determined. The differential scanning calorimetry and polarizing optical microscopy measurements confirm the existence of smectic A phase.</p> <p>Ultra Chemistry Vol. 3(2), 173-178 (2007).</p> https://journalofchemistry.org/paper/658/ Ultra Chemistry scanning calorimetry polarizing optical microscopy measurements
