Effective synergy of ionic capacity and C3-symmetry porosity in porous ionic polymers based imidazolium/pyridinium-benzene and/or triazine molecular hybrids: A comprehensive review

Abstract

The broad spectrum of applications and significance of C3-symmetric porous ionic polymers (C3-PiPs) have been demonstrated based on available literature. A comprehensive and thorough review of the numerous applications of C3-PiPs has been implemented, highlighting recent significant accomplishments across every area. Their structural arrangement, which is defined by threefold symmetry, confers distinct features and functions. The aforementioned materials unite the benefits of both porous frameworks and ionic interactions, resulting in higher adsorption, variable charge distribution, and significant stability. This overview is anticipated to enlightening the significant knowledge of all C3-PiPs-related research fields, focusing on the efficient four synthetic approaches for expanding the synthesis of C3-PiPs: post-synthesis polymer modification to enhance porosity and functionality, one-component self-condensation, multi-component co-polymerization and one-pot quaternization. Along with that, the challenges involved with the industrial application of ionic liquids have been noted, demanding further exploration.
