Unusual 3,4-Oxidative Coupling Polymerization on 1,2,5-Trisubstituted Pyrroles for Novel Porous Organic Polymers

Abstract

Porous organic polymers (POPs) have demonstrated promising task-specific applications due to their structure designability and thus functionality. Herein, an unusual 3,4polymerization on 1,2,5-trisubstituted pyrroles has been developed to give linear polypyrrole-3,4 in high efficiency, with Mn of 20000 and PDI of 1.7. This novel polymerization technique was applied to prepare a series of polypyrrole-based POPs (PY-POP-1−4), which exhibited high BET surface areas (up to 762 m 2 g −1 ) with a meso− micro−supermicro hierarchically porous structure. Furthermore, PY-POPs were doped in the mixed matrix membranes based on the polysulfone matrix to enhance the gas permeability and gas pair selectivity, with H 2 /N 2 selectivity up to 84.6 and CO 2 /CH 4 and CO 2 /N 2 selectivity up to 46.8 and 39.6.

Rapid and High-Density Antibody Immobilization Using Electropolymerization of Pyrrole for Highly Sensitive Immunoassay

“…In order to overcome the above-mentioned limitation, we designed an immobilization method for Abs to increase the Ab density based on the electropolymerization of pyrrole. Polypyrrole (Ppy) is a material of particular interest in EC sensors because of it has good biocompatibility and easy and simple immobilization of several biomolecules. − Various types of Ppy mixed layers are used for the selective detection of enzymes, , neurotransmitters, and catechols . Ppy is also used as a drug delivery material because it exhibits electrochemically induced volume change due to the movement of ions and solvents in and out of the polymer matrix when a potential is applied. , In our previous work, we synthesized various types of Ppy morphologies using sodium perchlorate (NaClO 4 ) as a dopant.…”
