Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - A new compounds of 2,4-substituted-1,3- thiazole containing amines [I] and [II], Schiff bases [IV] and [V], amides [VI]-[X],esters [XI] - [XIII], thiazolidinones [XIV]-[XVIII] and 1,3-oxazepines [XIX]-[XXV] were Synthesized and character…ized by melting points, FTIR spectroscopy, elemental analysis, 1HNMR,13CNMR, dept135and Mass spectroscopy. The liquid crystalline properties of the synthesized compounds were verified by using hot-stage polarizing optical microscopy (POM) and differential scanning calorimeter (DSC). The compound [I] was found to be nematic textures (N). The first series of this study [II]n display only enantiotropic nematic phase when n=1-5 while the compounds with n =6-8 display two mesophasese smectic C(SmC) and nematic phases(N). All compounds of series [IV]n were found to be enantiotropic nematic phase. Compounds[VI]a and[VI]b showed both semctic and nematic phases. Compounds [XI]a, b and [XIII]a, b showed only nematic texture but the compounds [XI]c and [XIII]c did not show any liquid crystalline properties. All compounds of series [XVII]n with n=1,3-7 display only nematic texture but compound with n=8 showed semactic C phase (SmC) in addition of ne.
