Three types of LC materials with isothiocyanate tolane group were prepared via couple and electronation reaction. These LCs exhibit a high birefringence
and the
n
increased with conjugation length of -electron
the maximal value among these LCs was 0.576. When these LCs were mixed in the commercial alkyne LCs respectively
the response performance of the device could be improved. These data demonstrates that the isothiocyanate tolane LCs have high
n
and low rotational viscosity
which can be used in the device of LC spatial modulator.
