Organic multilayer thin film deposition techniques

State-of- the-Ait in Organic Multilayer Thin Film Deposition Techniques. 

Fabrication of organic thin films based on sponfaneous molecular assembly has been considered as one of fhe powerful approaches to create novel supramolecular systems. In this context, multilayer films were fabricated by layer-by-layer electrostatic deposition techniques based on the electrostatic interaction between dsDNA and the positively charged polymer poly(diallyldimethylammonium chloride) (PDDA) on GC surfaces. A uniform assembly of PDDA/DNA multilayer films was achieved, based on the adsorption of the negatively charged DNA molecules on the positively charged substrate [55]. 

As already mentioned, a wide variety of photochemical and photophysical properties of clay-dye systems have been reported. Motivated by the progress in controlling photoprocesses by organizing species in the interlayer space of layCTed materials has led researchers to fabricate intercalation compounds as thin films. For such purposes, films with precisely controlled thickness and the multilayered structures with alternate heteroaggregates are required. Accordingly, the layer-by-layer deposition technique and the LB method have been conducted.
