Abstract: A compound with the phenyl-pyrazine skeleton and conjugate ene-yne structure was synthesized by the Sonogashira-coupling reaction under the palladium catalyst and copper (I) iodide. This compound shows a stable Smectic phase with the wide range of the temperature from 169℃ to 62℃ due to lengthening of π conjugate systems by introducing ene-yne structure. Moreover, this compound shows strong fluorescence due to decrease of the polarity of the phenyl-pyrazine skeleton by introducing the ene-yne structure.
