The modern ages have seen an embarking trend in the technology revolving around the organic solvent nanofiltration (OSN) that employs pressure gradient to separate molecules in the range of 200-1000 g/mol. The OSN technique generally provides better energy efficiency as compared to conventional practices such as chromatography or solvent extraction, primarily under mild condition. This one of the prime reasons the OSN technique is used in commercially viable sectors such as fuel industries and chemical plants. Amidst these advantages, the methodology is still in its evolutionary phase since the fabrication of a material which may be stable is various kinds of solvents is an arduous task for the researchers. Furthermore, a bolstered reproducible result is not obtained from this technique creating several loopholes while considering this operation. This short review refers to the recent works reported by Liang et al. using conjugated microporous polymer membrane fabricated by surface-initiated polymerization. The membranes not only exhibited a much-reinforced resistance to the organic solvents but also exhibited an enhanced efficacy when contrasted to hexane and methanol.
