The temperature dependence of the auxeticity of a special class of molecular auxetics, namely, a self\-expanding supramolecular network of auxegens containing alternating phenyl and acetylene links, is studied with use of this approximation method. The simulation results show that as temperature increases from 0 to 300 K, the auxeticity of the resulting superlattice or van der Waals network of auxegens decreases from the initial self\-expandability to two negatively small Poisson ratios on the xoy plane."]
