Further study about hydrocarbons/water separation was made by Yang et while using 4,4-bis(chloromethyl)biphenyl incorporated with triphenylamine. By changing the monomer ratio, a series of hypercrosslinked polymers were obtained with high surface areas and a predominantly microporous structure. With apparent BET surface areas of 1362 m g for PBP-N-25 and 1338 m g for PBP-N-50, the benzene/water vapor selectivity was as high as 53.5 and 63.6, respectively. Moreover, a monolithic polymer (M-PBP-N-25) was prepared with an apparent BET surface area of 551 m g. Owing to its hydrophobic nature and low density, the monolith showed the potential for applications in oil spill cleanup operations. 

Structure with high surface areas of up to 847 g for HCP-BDM and 742 g for HCP-BA. It is worth noting that the networks based on BA can
