2,3,6,7-Naphthalenetetracarboxylic dianhydride was prepared and characterized by UV, IR, and NMR spectra. Its structure was confirmed by single crystal X-ray determination. It is a moderate strength electron acceptor, stronger than p-benzoquinone and weaker than pyromellitic anhydride according to quantum mechanical calculations and electrochemical measurements.

aromatic protons exhibit strong solvent dependency; in particular, they are as sensitive as the proton in chloroform to the presence of DMSO. The vinylic protons activated by the electron-accepting COOR groups behave similarly. Quantum mechanical calculations in the gasphase and in DMSO reproduce the experimental observations.

Provided are a liquid crystal alignment film capable of being given anisotropy through photoalignment and stable to light, and a liquid crystal display device capable of keeping a high voltage holding ratio without degradation of display quality even when exposed to strong light for a long period of time. To provide these, used is a liquid crystal aligning agent for photoalignment which contains a polymer having a structural unit containing a photoreactive structure and in which the structural unit containing a photoreactive structure undergoes chemical reaction by heating.
