Connectors, antiferroelectrics

C1/C2 chevrons, ferroelectric devices 644 cadmium selenium TFT address 233 Cano wedge, chiral nematics 347 f, 351 Canon technology, ferroelectric devices 648 capillaiy flow, shear viscosity 143 carbocyclic compounds, charge transfer systems 958 carbocyclic rings, smectogens 412 carbon atoms, intercalated smectics 808 carbon-carbon bonds, dimers 823 carbon-carbon double bonds, chiral smectics 498 carbonaceous phases 693 carbonyl connectors, antiferroelectrics 687 carbonyl groups... 

Some connectors are listed in Figure 27(b). Almost all AFLC compounds have a carbonyloxy connector between the asymmetric carbon atom and the ring in the core, but some compounds [55] have a carbonyl or oxycarbonyl connector (Figure 29). Inui [56] studied the alkylcarbonyloxy connectors and found that -C2H4COO- exhibits antiferroelectricity but -CH2COO- does not although -CH=CH- is better regarded as included in the core, cinnamates also show antiferroelectricity.
