It is an object of the present invention to provide molecular compounds useful in the fields of state-of the-art materials, such as formulations, waste water treatments, energy transducers, conductors and bio-model reactions, in a way that interaction points and forces working inside polymer assemblies are fixed as well as controlled so that constituent polymers are aligned and modified. It is also an object of the present invention to provide methods for aligning and/or modifying polymers having hydrogen bond sites. A molecular compound is produced from a tetrakis aryl compound represented by Formula (I) (wherein, X is (CH.sub.2).sub.n, or p-phenylene; n is 0, 1, 2 or 3; Y is hydroxyl, carboxyl or optionally substituted amino: and R.sup.1 and R.sup.2 are each hydrogen, lower alkyl, optionally substituted phenyl, halogen or lower alkoxy) and a polymer having hydrogen bond sites, such as polyethers, polyalcohols or polyamines. ##STR00001##
