Perylene Diimide-Containing Dynamic Hyper-crosslinked Ionic Porous Organic Polymers: Modulation of Assembly and Gas Storage

Abstract

A strategy to synthesize hyper-crosslinked polymers with strong visible-light absorption and abundant ionic sites is discussed. This is achieved in a one-pot reaction via the simultaneous Friedel–Crafts alkylation and quaternization reaction between α,α′-dibromo-p-xylene (DBX) and perylene diimide (PDI) substituted with N,N-dimethyl ethylene to result in hyper-crosslinked ionic polymers (HIPs). These HIPs display good surface areas with strong visible-light absorption (400–650 nm) and dispersibility in polar solvents like water and DMSO. Importantly, our experimental and theoretical studies indicate that PDI-HIPs possess a dynamic network with good uptake of water up to seven times their weight. Notably, PDI in PDI-HIPs is not only responsible for visible-light absorption but also acts as a probe to study their dynamic nature. Moreover, the presence of ultramicropores and CO2-philic functional groups in PDI-HIPs renders good CO2 uptake up to 2.11 mmol/g at 273 K despite their relatively low surface area.

Pathway Selection in Temporal Evolution of Supramolecular Polymers of Ionic π‐Systems: Amphiphilic Organic Solvent Dictates the Fate of Water

“…In sharp contrast, we also found that hierarchical self‐assembly can also occur by increasing solvated solute concentration and without much release of solvent molecules from the solute (Pathwa‐2). Our findings further suggest that the water‐AOS mixture is an exciting solvent medium for uncovering new solvation‐desolvation phenomena in polymeric and supramolecular polymeric systems and synthesizing functional soft materials [63] …”

Supramolecular Engineering of Ti3C2Tx MXene ‐Perylene Diimide Hybrid Electrodes for the Pseudocapacitive Electrochemical Storage of Calcium Ions

“…Synthesis of cPDI: cPDI has been synthesized according to the literature methods. [62,63] Preparation of cPDI involves a two-step reaction, in the first phase PDI was prepared by adding 3,4,9,10 perylene tetracarboxylic dianhydride (1 g, 2.55 mmol) and N,N-dimethylethylenediamine (0.89 g, 10.19 mmol) to the imidazole (10 g) and the reaction was carried out for 8 h at 120 °C. The obtained precipitate was filtered and washed repeatedly with methanol to remove the imidazole.…”

Study on naphthalene ring-linked metalloporphyrin-conjugated microporous polymers with enhanced visible photocatalytic activity

“…The conjugated microporous polymer (CMP) is a new type of porous material made only from covalent bonds and exhibits a rigid backbone, large surface area, and high stability. [5] Various organic building blocks have been used to synthesize the CMP, and the CMP plays an important role in applications such as gas storage, [6] catalysis, [7] and sensing, [8] etc. The incorporation of porphyrin into CMP reduces porphyrin aggregation, which in turn enhances its photocatalytic degradation performance.…”
