Synthesis, characterization and properties of N-maleimide side-chain liquid crystalline copolymers

A homologous series of side-chain liquid crystalline (SCLC) poly{[N-[10-((4-(((4′-n-hexyloxy)benzoyl)oxy)phenoxy)carbonyl)-n-decyl] maleimide]-co-[N-(n-octadecyl)maleimide]} [(ME6)-co-(MI-18)] random copolymers with various MI-18 contents have been synthesized and their properties studied. The high content in threo-disyndiotactic sequences of the maleimide main chain seems responsible for the stability of the highly ordered smectic mesophase. The relationship between structure and composition on thermotropic mesophase was investigated by polarizing optical microscopy, differential scanning calorimetry, and X-ray diffraction. For copolymers with mesogenic unit contents less than ～0.655 molar fraction the transition from (SA) texture to isotropic (I) is maintained, as shown by the TCl, ΔH Cl and ΔSCl amounts and intermolecular spacing 4.42-4.53 A and intralayer correlation lengths of 44.2-45.2 A. The layer thickness does not appreciably depend on copolymer composition. However, copolymers with non-mesogenic comonomer MI-18 molar contents larger than >0.655 molar fraction X(M), are no longer liquid crystalline materials, despite its packing is preserved without any detectable appearance of birefringence. Thermodynamic boundaries of the liquid crystalline state have been established through a phase diagram. The properties of this n-hexyloxy pendant group-based series are compared to those of the analogous materials containing methoxy pendant groups (ME1), and differences are accounted for in terms of the local side-chain packing within the mesophase.

Orientational order in the cholesteric phase of new optically active phenyl benzoates

Three new optically active phenyl benzoates were synthesized, and their phase behavior was studied by differential scanning calorimetry and optical microscopy. It was established that the obtained substances form more than one crystalline modification, as

Study of activation energy and order of reaction of some liquid crystals

Liquid crystals of the type p-phenylene-di-p-n-alkoxy benzoate have been prepared. Kissinger isothermal decomposition method has been used for determination of activation energy values of liquid crystals. Kissinger's assessment for shape index of DTA peaks is used to find the order of reaction. There is no direct relationship between the carbon atoms in terminal methylene groups and Ea values. Order of reaction value decreases with increase in heating rate upto carbon atoms 10 in the terminal methylene group but beyond this the order increases or decreases.

The two series I and II of 1,1'-disubstituted ferrocenes which differ by the direction of the ester function included the rigid organic part were synthesized and their liquid crystal properties examined.These latter were found to be strongly dependent on the orientation of the connecting ester group and on the alkyl chain.

FERROELECTRIC SC* PHASE IN SOME BENZOATE SERIES

Several homologous benzoate series which exhibit ferroelectric smectic SC* phases have been synthesized.The used chiral acid chains were prepared from commercially available α-amino acids.The series allow us to determine the influence of the size of the substituent of the chiral carbon on the existence and the stability of the SC* phase.They also give some compounds or mixtures which display high spontaneous polarization.
