Diamino compounds and methods for preparing them

An object of the invention is to propose diamino compounds expressed by the following general formula (1) which are suitable to obtain a raw material, a polyimide resin, for a liquid crystal aligning film without any image sticking and with a high voltage holding ratio at from a low temperature to a high temperature as well as the preparation thereof: STR1

(1.1.1.1.1)PARACYCLOPHANE AND (1.1.1.1.1.1)PARACYCLOPHANE

The first syntheses of (1.1.1.1.1)paracyclophane (1) and (1.1.1.1.1.1)paracyclophane (2) are described, featuring a trifluoroacetic acid promoted Friedel-Crafts cycloalkylation as the final step.
