A variety of chiral dopants from optically active 2.4-pentanediole were prepared
The temperature coefficient of the induced cholesteric pitch of compound(A) was measured to show that dP/dT depended on substituent group R. When R─CH3 and CH3O, compounds(A) shows positive dP/dT. But when R=Benzonitrile group, compound(A) shows negative dP/dT.
