    Sammanfattning : Microporous organic polymers (MOPs) are porous materials. Owing to their high surface area, tunable pore sizes and high physicochemical stability, they are studied for applications including gas capture and separation and heterogeneous catalysis. In this thesis, a series of imine/azo-linked MOPs were synthesized. LÄS MER

  3. 2. Thermal Isomerization of Azobenzene Side Chain Copolymers

    Författare :Viktoria Skeppstedt; Chalmers tekniska högskola; []

    Sammanfattning : Irradiation of azobenzene induces isomerization between its trans- and cis forms. By introduction of azobenzene chromophores in polymers, it is possible to optically control a variety of polymer properties. The isomerization of azobenzene can be used to influence conformational, optical or surface properties of the poly mer material. LÄS MER
