Nematic Materials for Direct Addressing

Parentheses represent a monotropic transition temperature brackets represent a virtual, extrapolated transition temperature a SmA phase at 93.5°C. 

Parentheses represents a monotropic transition temperature SmB phase at 94°C Ac measured at 0.98 X Tni 42°C 25X. 

If the cyano group is attached to a non-conjugated alicyclic ring, as in the aliphatic nitriles (54-59) also collated in Table then the dipole moment 

The rfl j-l- -alkyl-4-(4-cyanophenyl)cyclohexanes exhibited an unparalleled advantageous combination of physical properties for TN-LCDs at this time. Therefore, a central linkage was incorporated between the cyclohexane and the phenyl ring of PCH-5 (41) to form the structurally related compounds (6(1-69) collated in Table 3.6 in attempts to improve on these properties. However, only the /ra j -l- -alkyl-4-[2-(4-cyanophenyl)ethyl]cyclohexanes (PECHs), e.g. PECH-5 (62), were almost equivalent from the point of view of 

Parentheses represent a monotropic transition temperature monotropic SmX-SmB transition at
