An ultrathin composite film containing cationic tetra-pyridine perylene tetracarboxylic acid diimide (TPP-I) and an anionic tetra-sulfuric perylene tetracarboxylic acid diimide (TSP-Na) has been fabricated by the electrostatic layer-by-layer self-assembly technique. UV/Vis spectra showed a continuous and uniform deposition process of TPP-I/TSP-Na. The film structure was characterized by the small-angle...
An ultrathin nanoscopic multilayer film has been fabricated through the electrostatic layer-by-layer self-assembly of water-soluble porphyrin derivative 5,10,15,20-tetrakis-(3,4,5-trihydroxy-phenyl)-porphyrine (DHP) and oppositely charged poly{(2, 5-bis (3-bromotrimethylammoniopropoxy)-phenylene-1, 4-divinylene)-alt-1, 4-(2, 5-bis (2-(2-hydroxyethoxy) ethoxy))phenylenevinylene} (BH-PPV). UV-vis spectra...
