摘要:The present invention is relates to the synthesis of predominantly planar heterocyclic organic compound and the manufacture of optical films based on these compounds. Said organic compound has the general structural formula where Het is a predominantly planar heterocyclic molecular system possessing hydrophilic properties; B is a binding group; p is the number in the range from 3 to 8; S is a group providing solubility of the organic compound; m is a number in the range from 0 to 8. Said organic compound is transparent for electromagnetic radiation in the visible spectral range from 400 to 700 nm, and a solution of the compound or a salt thereof is capable of forming a substantially transparent optical layer on a substrate, with the heterocyclic molecular planes oriented predominantly parallel to the substrate surface.
