| 제목 | Towards the Design of Functional Polymers: Controlled Radical Polymerization of Reactive Monomers |
| 초록 | With the emerging of interdisciplinary sciences, such as nanotechnologies and bionanotechnologies, the necessity of new designed materials is steadily growing. Polymers play and will play an important role in these newly emerging scientific areas. Therefore, the synthesis of defined polymer architectures and polymer functionalities is a continually rising research focus. Recently, various controlled radical polymerization techniques have proved to be versatile methods to polymerize a variety of monomers, thus having good control of polymer architectures. Recently, we developed synthetic strategies to prepare reactive pre-polymers and pre-block copolymers, which form the basis for designing new and highly efficient functional polymeric materials. Accordingly, we could describe pentafluorophenyl acrylates as a new class of active ester monomers. Further, we have succeeded in the controlled radical polymerization of endo-N-hydroxy-5-norbornene-2,3-dicarboxyimide acrylate via ATRP, laying the basis to prepare functionalized block copolymers. Within the present contribution, we want to present further reactive monomers which are capable to be polymerized under controlled radical polymerization conditions. The class of acrylate based reactive monomers was successfully extended to styrene based active monomers. So far, mainly active esters are successfully used as reactive groups within monomers and polymers. But also the introduction of new reactive groups will be presented. This results in a comprehensive toolbox for designing functional polymers. With such methods in hand, functional homo- and co-polymers were synthesized for various applications such as functionalization of interfaces via self-assembly. For example, various polymer functionalized nano TiO2 particles will be shown. Furthermore, immobilization of lipid bilayers or functional proteins onto interfaces are examples of the broad application spectra using our design routes of reactive polymers in the area of self-assembled functional materials. But also solution self-organization processes will be discussed. Figure 1: CLSM pictures of polymer functionalized TiO2 nanowires. References: 1. P. Theato, R. Zentel, J. Col.
