Abstract: Abstract A homologous series of ketone-type liquid crystal (LC) dimers, namely carbonyl- and thioether-linked cyanobiphenyl-based bent LC dimers (CBCOnSCB), with odd numbers of alkylene spacers (n = 3, 5, 7, and 9), was developed. CBCOnSCB dimers (n = 3,… read more here.

Abstract: We herein report phase transitions, mesomorphism, birefringence behavior and photoluminescence properties of symmetric liquid crystal (LC) dimers based on diphenylacetylene or tolane. A homologous series of 4-methoxy tolanes linked with oligomethylene spacers consisting of carbon… read more here.
