Thermotropic - Opis:
- A novel homologous series of liquid crystalline materials of schiff’s bases viz. RO-C6H4-CH=CH-COO-C6H4-N=CH-C6H4-NO2 is synthesized and studied with a view to understanding and establishing the effect of molecular structure on liquid crystal properties and to provide novel thermotropic LC material to the scientific and technological community of research interest. The novel series consist of 12 homologues. All members of the series are enantiotropically smectogenic character. The transition temperatures were determined by an optical polarizing microscopy equipped with a heating stage. Thermal stability of smectogenic mesophase is 132.2 °C and mesophase length is varies between 4.7 °C to 32.7 °C. The LC behaviour of the novel series compared with a structurally similar known series.
