C. Zuniga et al., SYNTHESIS AND MESOMORPHIC PROPERTIES OF 6-N-DECYLOXY-2-[4'-N-ALKOXYPHENYLIMINO)METHYL] QUINOLINES .4., Liquid crystals, 20(2), 1996, pp. 253-260
The synthesis and mesomorphic properties of a new series of liquid cry
stals derived from quinoline with an imine central bond is described.
All compounds exhibit mesophase ranges greater than 50 degrees C. The
lower homologues (n=4-6) show trimorphism S-C-S-A-N (for n=4, the S-C
phase is monotropic). The higher homologues (n=7-10) show nematic and
smectic C phases. Compared to the styrylquinoline analogues the imine
bond gives rise to similar liquid crystal phase ranges but lower melti
ng points.
