Processable Conjugated Microporous Polymer Gels and Monoliths: Fundamentals and Versatile Applications

Abstract

Conjugated microporous polymers (CMPs) as a new type of conjugated polymers have attracted extensive attention in academia and industry because of the combination of microporous structure and π-electron conjugated structure. The construction and application of gels and monoliths based on CMPs constitute a fertile area of research, promising to provide solutions to complex environmental and energy issues. This review summarizes and objectively analyzes the latest advances in the construction and application of processable CMP gels and monoliths, linking the basic and enhanced properties to widespread applications. In this review, we open with a summary of the construction methods used to build CMP gels and monoliths and assess the feasibility of different preparation techniques and the advantages of the products. The CMP gels and monoliths with enhanced properties involving various special applications are then deliberated by highlighting relevant scientific literature and discussions. Finally, we present the issues and future of openness in the field, as well as come up with the major challenges hindering further development, to guide researchers in this field.

Impact of the Crystallinity of Covalent Organic Frameworks on Photocatalytic Hydrogen Evolution

“…The field of porous materials has expanded since the beginning of this century from traditional inorganic materials to crystalline covalent organic frameworks (COFs). − The design and synthesis of porous materials is a frontier field of research due to their wide range of applications, including gas capture and separation, − water treatment, , energy storage, − and heterogeneous catalysis. − Based on the degree of long-range structural ordering, porous materials can be classified as amorphous and crystalline. Hyper-cross-linked polymers (HCPs), polymers of intrinsic microporosity (PIMs), , and conjugated microporous polymers (CMPs) , are classified as amorphous, whereas zeolites, , MOFs, porous molecular cages, , and COFs fall into the class of porous crystalline materials. Unlike traditional porous organic polymers (such as linear, branched, or cross-linked polymers), COFs exhibit long-range ordering, designable structures, and uniform and nanometer-scale pores .…”

Efficient faradaic supercapacitor energy storage using redox-active pyrene- and benzodithiophene-4,8-dione-tethered conjugated microporous polymers

“…[35][36][37][38][39][40][41] Even though CMPs have been employed in numerous elds, including photocatalysis, drug delivery, gas storage, gas separation, dye removal, and uorescence detection, their uses as SCs electrodes are restricted by their subpar conductivity, which signicantly decreases their capacitance. [42][43][44][45][46][47][48][49][50][51][52][53][54] CMPs are generally mixed with other conductive materials to boost the conductivity of CMP-based electrodes. Unfortunately, it is challenging to considerably improve the CMP performance due to the poor connection between the CMP and conductor.…”

Anti‐Counterfeiting Application of Persistent Luminescence Materials and Its Research Progress

“…Among them, luminescence-based persistent luminescent (PersL) anti-counterfeiting materials have attracted widespread attention due to their easy implementation, good concealment, difficulty in replication, high emission intensity, multiple emission colors, long emission life, and applicability to mass production. [33][34][35][36][37] PersL materials have been widely studied and applied in the fields of special lighting, [38,39] light storage [40,41] and military engineering [42,43] because of their characteristics of continuous luminescence under dark conditions, however, the application in the field of dynamic anti-counterfeiting technology is rare. We have combined PersL materials and anti-counterfeiting applications and found that dynamic anticounterfeiting marking applications can be prepared.…”
