Poly self-organizing behavior

Recently, the enhanced control of bulk and surface ordering of polypeptides has been employed to drive the processing and self-assembly of conductive rigid segments. Mainly triblock copolymer structures have been studied (see the following section). Manners and Winnik (Wang et al., 2008) synthesized a new type of metaUopolymer-polypeptide block copolymer poly(ferrocenyldimethylsilane)-fc-poly(8-benzyloxycarbonyl-L-lysine) (PFS-( -PZLLys) and studied their self-organization behavior in both the bulk state and in solution. In the bulk state, a cylindrical in-lamellar structure was observed in a compositionally asymmetric sample. Rod-like micelles with a polyferrocenylsilane core formed in a polypeptide selective solvent alone or in the presence of a common solvent.

A multistep reaction pathway leads to polymers 43 and 44 with phosphatidylcholine moieties in the main chain and long alkyl groups in the side chain [122]. These polymers exhibit thermotropic liquid-crystalline behavior. Polyamides 45 were obtained by interfacial polycondensation they are insoluble in any normal solvent [123]. Poly-MPC capped with cholesteryl moieties at one or both polymer ends was prepared by the radical polymerization of MFC initiated with 4,4 -azobis[(3-cholesteryl)-4-cyanopentanoate] in the presence of a chain transfer agent [124]. The self-organization of these polymers was analyzed with fluorescence and NMR measurements.

Self-organized honeycomb morphologies [60] have recently been identified with well-defined hompol)mieric star-shaped PS (or on polydisperse starshaped polymers or copol)miers). That morphology was observed first on poly-st5n-ene-polyparaphenylene block copolymers and may be attributed for linear or branched polyst)n-enes to the specific behavior of PS in carbon disulfide [61].
