Three SSCs are prepared from the melitose core and the side
arms with different terminal chain (b1–b3). They exhibit levo spe-
cific rotation and the absolute value of specific rotation increases
with the increase of terminal chain length in the side arms.
The appearance of LC properties of SSCs depends on the proper-
ties of side arms. Only when the side arm is a LC, the SSCs display
LC properties. b1 and c1 are non-LC compounds. b2, c2 and b3, c3
exhibit mesomorphic properties. The length of terminal chain of
side arms also affects the phase transition temperature of SSCs.
For c1–c3, with the increase of terminal chain, the melting temper-
ature decreases. For c2 and c3, with the increase of terminal chain,
