A New Strategy to Microporous Polymers: Knitting Rigid Aromatic Building Blocks by External Cross-Linker
(2410–2414) Macromolecules 44 #8 (2011)
Li et al of Huazhong University of Science and Technology and Lanzhou University, China, obtained a series of microporous polymers  via a low-cost versatile strategy, by “knitting” rigid aromatic building blocks, such as benzene, biphenyl, 1,3,5-triphenylbenzene, methylbenzene, chlorobenzene, and phenol using an external cross-linker.  These materials are predominantly microporous and exhibit high surface areas. Moreover, different building blocks can generate materials with different pore structures, functional groups and application properties, which are significant for materials design.  (RDC 5/27/2011
