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

[Display omitted] •A comprehensive of the most prominent and efficient methods for synthesizing tunable materials out of C3-PiPs.•In-depth review along with the most numerous applications for tunable materials out of C3-PiPs.•Significant and most recent accomplishments in various areas have been highlighted.•Substantial concepts of all C3-PiPs-related research fields have been reported.•The effective synthetic approaches adopted for the synthesis of these tunable C3-PiPs have been well discussed. 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 enlighteningthe significant knowledge of all C3-PiPs-related research fields, focusing on the efficient four synthetic approaches forexpanding the synthesis of C3-PiPs: post-synthesis polymer modification to enhance porosity and functionality, one-component self-condensation, multi-component co-polymerizationand one-pot quaternization. Along with that, the challenges involved with the industrial application of ionic liquids have been noted, demanding furtherexploration.
