Assembly poly -containing films

We have employed a related approach in generating films containing alternating layers of the anionic, water-soluble sulfonated polyaniline PMAS 9 and the polycation, poly(vinylpyridine).164 The analogous self-assembly of multilayer films of the sulfonated SPAN 8 and the light-sensitive polycation, diazoresin, has also been described recently.165... 

Summary Well-defined amphiphilic block copolymers containing a poly(dimethyl siloxane) (PDMS) and a poly(ethylene oxide) (PEO) block were synthesized by ringopening polymerization of hexamethylcyclotrisiloxane, followed by chain extension with a PEO block of a defined length. These amphiphilic molecules were used as structure-directing agents in a solvent evaporation-driven synthesis approach to self-assembled mesostructured silica films. In addition, a general theoretical approach for an understanding and ultimately a prediction of the phase behaviour of block copolymers is presented. 

Another type of noncovalent interaction, namely electrostatic ones, has recently been exploited by Wang et al. in the fabrication of a hybrid film containing a water-soluble poly(thiophene) derivative and CdSe NCs.141 In this case CdSe NCs were functionalized with 11-mercaptoundecanonic acid (MUA) molecules prior to their self-assembly with side chain-functionalized poly(thiophene), that is, poly(3-(3 -thienyloxy)propyltrimethylammonium bromide) (P3TOPA).
