Abstract： |
The invention discloses a diphenylacetylene derivative, its preparing process and use, wherein the derivative has structural formula I, wherein R is alkyl, m is 0 or 1. By introducing a methoxyl onto the lateral direction of the molecule, the diphenylacetylene derivative can increase the width of the liquid crystal molecules, improve dissolution property, and keep the large optical birefringent of the liquid crystal molecules. |
