Diamine compound, polyamic acid, polyimide, and liquid crystal aligning agent |
| abstract |
Provided is a novel diamine compound useful as a raw material for a polyamic acid and/or polyimide. The polyamic acid or polyimide prepared using the diamine compound can constitute a liquid crystal aligning agent capable of forming a liquid crystal alignment film which has a high voltage holding ratio and which, even after long-time exposure to high temperature, achieves quick relaxation of a residual charge accumulated by DC voltage. Specifically provided are a novel dimaine compound represented by general formula [1], and a liquid crystal aligning agent which contains a polyamic acid and/or polyimide prepared using the diamine compound. In general formula [1], X1 is -CO- or -CONH-; X2 is a C1-5 alkylene group or a nitrogen-containing nonaromatic heterocycle; and X3 is a five- or six-membered aromatic heterocycle which contains two nitrogen atoms and which may be substituted with a C1-5 alkyl group. |
