While the synergistic “trap-and-destroy” pathway—combining rapid adsorption with in-situ photocatalytic degradation—is highly promising, its practical deployment is often hindered by the aggregation-caused quenching (ACQ) of organic chromophores and the recovery challenges associated with suspended powder catalysts. This work proposes a topology-directed engineering strategy to fabricate a macroscopic, metal-free material (PCSOA) by crosslinking perylene diimides with rigid polyhedral oligomeric silsesquioxane (POSS or SQs) cages. DFT calculations suggest that the rigid POSS nodes provide strong structural constraint to restrict the molecular motion of the photoactive perylene units, thereby suppressing non-radiative decay pathways while largely preserving the intrinsic frontier molecular orbitals. Driven by strong electrostatic and π-π affinities, the highly polarized network captures trinitrophenol with an uptake reaching 929 mg g⁻¹. By gathering target molecules directly around the active sites, this localized accumulation significantly enhances visible-light photoactivity. Consequently, the system delivers a phenol mineralization rate constant of 1.79 h⁻¹ and removes over 98% of the total organic carbon (TOC). From a practical standpoint, formatting the material into a macroscopic aerogel bypasses the cumbersome separation steps inherent to powders, allowing for stable and high-throughput water treatment in continuous-flow setups.</p>\u0000 </div>","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":"47 20","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148757256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Developing solid hygroscopic materials that simultaneously achieve high moisture uptake, low-temperature regeneration, and rapid adsorption kinetics remains a significant challenge. Herein, we report a porous hygroscopic superabsorbent polymer, porous poly(acrylic acid-co-sodium acrylate) (PPAANa), synthesized via high internal phase emulsion (HIPE) templating coupled with high-speed shearing homogenization and a polymerizable macromolecular surfactant. At 25°C, PPAANa achieves a moisture uptake of 0.76 g g⁻¹ within 45 min at 70% relative humidity (RH) and 1.53 g g⁻¹ within 105 min under 90% RH, demonstrating high capacity and fast kinetics. Moreover, 90% of the adsorbed water was released within 20 min under a low regeneration temperature of 60°C (20% RH), underscoring its fast and energy-efficient desorption performance. Additionally, a small dosage of PPAANa (0.125 g L⁻¹) reduces the RH from 90% to 58% within 1 h at 25°C. Conversely, when pre-loaded with 0.25–0.45 g g⁻¹ of water, it raises the RH from 30% to a tunable range of 42%–59% under the same conditions.

During curing, the block copolymer undergoes crystallization-driven self-assembly, generating micrometer-long nanoribbons that act as reversible thermal switching domains, while gold nanoparticles are simultaneously formed in situ, enabling efficient conversion of visible light into localized heat through plasmonic excitation. Spectroscopic and microscopic analyses confirm the successful incorporation of both components without compromising their native morphology. Differential scanning calorimetry reveals two distinct thermal events corresponding to the glass transition of the epoxy matrix and the melting of the polyethylene domains, providing two independently addressable switching temperatures. Under green-light irradiation, the embedded gold nanoparticles rapidly raise the local temperature, enabling not only remote activation of the shape-memory effect but also programmable sequential shape recovery by selectively activating each thermal transition through laser power adjustment.

Herein, we report a versatile approach exploring the synthesis of polymeric polyaldehydes (PP-CHO) with a polyacrylate backbone bearing pendant aldehyde groups to develop self-healable, reprocessable polyacrylate-PI hybrid CANs. The approach centers on the synthesis of well-defined poly(2-hydroxyethyl acrylate) bearing aldehyde pendants (PHEA-CHO) by a photo-indued reversible deactivation radical polymerization,(Photo-RDRP) followed by post-polymerization modification. The PHEA-CHO is highly reactive to an aliphatic diamine, enabling the fabrication of transparent, integrated, dynamic PHEA-PI hybrid CAN films. They exhibit lower activation energy (E_a = 14.6 kcal/mol) for stress relaxation even at mild temperature (50°C – 80°C) and good self-healability and reprocessability as retaining their mechanical strengths upon a recycle. Promisingly, they degrade to corresponding aldehyde and amine precursors through acid-catalyzed hydrolysis of benzoic imine crosslinks, offering potential for sustainability as recyclable dynamic covalent systems.

However, conventional petroleum-based aromatic PIs suffer from intrinsic coloration arising from charge-transfer complex (CTC) formation, limiting their optoelectronic applications. In this study, two camphor-derived alicyclic diamines (CA and CM) were synthesized, along with a reference isosorbide-derived diamine (IS). These monomers were polymerized with 1,2,3,4-cyclobutanetetracarboxylic dianhydride (CB) and a tetracarboxylic dianhydride featuring a cyclopentanone bis-spironorbornane structure (Cp) to prepare six biobased CPIs. Their favorable optical transparency arises from the combined contribution of the non-conjugated dianhydride structures and the alicyclic camphor-derived diamine structures. The structure–property relationships of the biobased CPIs were systematically investigated. The CA series exhibits limited film-forming ability because of its highly rigid molecular structure. In contrast, incorporating a methylene spacer into the CM series enhanced chain flexibility, leading to improved film-forming ability and overall film quality. Among the prepared CPIs, CM–CB exhibited the most balanced performance, achieving 60% biomass content, optical transparency (<i>T</i>₄₀₀ = 82% and <i>YI</i> = 3), and a glass transition temperature above 300°C.
