The synthesis, structural and mesomorphic characterization of new pyridine-based Me esters carrying a n-alkoxy chain or 3,7-dimethyloctyloxy branched group at terminal I [R = C8H17, C10H21, C12H25, (4S)-4,8-dimethylnonyl, 4,8-dimethylnonyl] have been presented. The liquid crystalline properties of the new pyridine-based calamitic mols. have been investigated by polarized optical microscopy and differential scanning calorimetry. New compounds exhibit enantiotropic smectic A mesophase at a variable mesomorphic range depending on alkoxy chain length and branching at terminal. The presence of a branched terminal group in chiral or racemic form gives rise to a sharply increase in mesomorphic range as well as decrease in crystallization points by preserving mesophase type. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Category: alcohols-buliding-blocks).
3,7-Dimethyloctan-1-ol (cas: 106-21-8) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Category: alcohols-buliding-blocks
