Conjugated Microporous Polymers

As a kind of ideal porous absorbents with tunable porosity, large surface areas, and hydrophobicity, conjugated microporous polymers (CMPs) have recently received extensive attention in oil/organic solvent-water separation. However, reports on the application of CMPs in adsorption of erythromycin (ERY) from water are very few. In this work, the adsorption of ERY by three kinds of CMPs was firstly studied. It was observed that all the CMPs extracted ERY quickly from water. The adsorption kinetics of ERY on the three CMPs was well expressed by the pseudo-second-order model, and the adsorption process was found to be mainly controlled by film diffusion. Increasing surface area of the CMPs resulted in greater extent of adsorption. This work may provide fundamental guidance for removal of antibiotics by CMPs.

Conjugated Microporous Polymers

Conjugated microporous polymers (CMPs) with robust architectures, facilely tunable pore sizes and large specific surface areas have emerged as an important class of porous materials due to their demonstrated prospects in various fields, e.g. gas storage/separation and heterogeneous catalysis. Herein, two new pyrrole-based CMPs with large specific surface areas and good stabilities were successfully prepared by one-step oxidative self-polycondensation of 1,2,4,5-tetra (pyrrol-2-ly)benzene or 1,3,5-tri (pyrrol-2-ly)benzene, respectively. Interestingly, both CMPs showed very high catalytic activity toward Knoevenagel condensation reaction, which was attributed to the inherent pore channels, high specific surface areas and abundant nitrogen sites within CMPs. Additionally, both CMPs displayed excellent recyclability with negligible degradation after 10 cycles. This work provides new possibilities into designing novel nitrogen-rich high-performance heterogeneous catalysts.
