Inkjet composition

摘要

A printed deposit comprising a self-assembled supramolecular polymer formed by &pgr;- &pgr; stacking interactions between at least a portion of a first polymer (preferably an electron-rich chromophore comprising an aromatic or heteroaromatic ring, such as pyrenyl or naphthyl) and at least a portion of a second polymer (preferably an electron-deficient chromophore comprising an alkene or an aromatic or heteroaromatic moiety, such as a naphthalene diimide or a dinitrofluorenone). An ink composition suitable for forming the deposit of the self-assembled supramolecular polymer comprising a solvent and a first and a second polymer, wherein at least a portion of the first polymer is capable of forming &pgr;- &pgr; stacking interactions with at least a portion of the second polymer to form the self-assembled supramolecule.
