- Side-chain liquid-crystalline polymer tetrazoles: Synthesis and characterization
-
The synthesis and phase behavior of three new side-chain liquid crystal polymers with short and long flexible alkyl spacers are described. These new materials show smectic C (SmC) mesophase. X-ray analysis for two samples has revealed that SmC mesophase displays partial interdigitation for the polymer with short flexible spacer, while for long flexible spacer polymer no interdigitation was observed. ?2014 Sociedade Brasileira de Qui?mica.
