The structure-property relationships of Polymers of Intrinsic Microporosity (PIMs)
نویسندگان
چکیده
Based on almost 20 years of published research, the structure-property relationships Polymers Intrinsic Microporosity (PIMs) are considered. Following an analysis structure archetypal PIM-1 and how it contributes to its now well-understood properties, key properties solubility, thermal gas adsorption permeability related structures more recently prepared PIMs. In order deliver their technological potential, is recommended that further synthetic effort should focus both broadening structural diversity PIMs providing synthetically accessible variants.

Microporous polymers derived from the 1,2- and 1,4-regioisomers of di(3',4'-dihydroxyphenyl)tetraphenylbenzene have very different properties with the former being composed predominantly of cyclic oligomers whereas the latter is of high molar mass suitable for the formation of robust solvent-cast films of high gas permeability.
