Abstract : A new series of water soluble conjugated aromatic polyimines containing sulfonate groups have been synthesized via polycondensation reaction between diamines and dialdehydes at room temperature. The polymers are soluble in water and N, N-diamethylformamide (DMF), giving colored solutions with absorption maxima (gammamax) ranging from 400 to 480nm. One of the polyimines (PIP) showed strong fluorescence in aqueous solution and concentration dependence of photo luminescence has been investigated. Electrostatic self assembly of multilayer films consisting of each polyimine as a polyanion and poly(diallyldimethylammonium chloride) as a polycation was successfully carried out by alternate deposition in corresponding aqueous solutions.
