FitzSimons, Thomas M.;Oentoro, Felicia;Shanbhag, Tej V.;Anslyn, Eric V.;Rosales, Adrianne M. research published 《 Preferential Control of Forward Reaction Kinetics in Hydrogels Crosslinked with Reversible Conjugate Additions》, the research content is summarized as follows. Mol. substitutions were used to demonstrate preferential control over the kinetic rate constants in a poly(ethylene glycol)-based hydrogel with two different reversible thia-conjugate addition reactions. A strong electron-withdrawing nitrile group on the conjugate acceptor showed a 20-fold increase in the forward rate constant over a neutral withdrawing group, whereas the reverse rate constant only increased 6-fold. Rheometry experiments demonstrated that the hydrogel plateau modulus was primarily dictated by reaction equilibrium, whereas the stress relaxation characteristics of the hydrogel were dominated by the reverse rate constant Furthermore, dynamic crosslinking allowed the hydrogel to rapidly and spontaneously self-heal. These results indicate that decoupling the kinetic rate constants of bond exchange allow systematic control over dynamic covalent hydrogel bulk properties, such as their adaptability, stress relaxation ability, and self-healing properties.

Corrado, Tanner J.;Huang, Zihan;Huang, Dezhao;Wamble, Noah;Luo, Tengfei;Guo, Ruilan research published 《 Pentiptycene-based ladder polymers with configurational free volume for enhanced gas separation performance and physical aging resistance》, the research content is summarized as follows. Polymers of intrinsic microporosity (PIMs) have shown promise in pushing the limits of gas separation membranes, recently redefining upper bounds for a variety of gas pair separations However, many of these membranes still suffer from reductions in permeability over time, removing the primary advantage of this class of polymer. In this work, a series of pentiptycene-based PIMs incorporated into copolymers with PIM-1 are examined to identify fundamental structure-property relationships between the configuration of the pentiptycene backbone and its accompanying linear or branched substituent group. The incorporation of pentiptycene provides a route to instill a more permanent, configuration-based free volume, resistant to phys. aging via traditional collapse of conformation-based free volume PPIM-i.p.-C and PPIM-np-S, copolymers with C- and S-shape backbones and branched isopropoxy and linear n-propoxy substituent groups, resp., each exhibited initial separation performance enhancements relative to PIM-1. Addnl., aging-enhanced gas permeabilities were observed, a stark departure from the typical permeability losses pure PIM-1 experiences with aging. Mixed-gas separation data showed enhanced CO2/CH4 selectivity relative to the pure-gas permeation results, with only ∼20% decreases in selectivity when moving from a CO2 partial pressure of ∼2.4 to ∼7.1 atm (atm. pressure) when utilizing a mixed-gas CO2/CH4 feed stream. These results highlight the potential of pentiptycene’s intrinsic, configurational free volume for simultaneously delivering size-sieving above the 2008 upper bound, along with exceptional resistance to phys. aging that often plagues high free volume PIMs.

Cosey, Whitney K.;Balkus, Kenneth J. Jr.;Ferraris, John P.;Musselman, Inga H. research published 《 Reduced Aging in Carbon Molecular Sieve Membranes Derived from PIM-1 and MOP-18》, the research content is summarized as follows. Carbon mol. sieve membranes (CMSMs) commonly lose permeability over time due to the collapse of micropores. This decline in permeability, due to the densification of the membrane, is known as phys. aging. CMSMs derived from polymers of intrinsic microporosity (PIM-1) are highly affected by phys. aging, with declines in permeability greater than 60% over time. The densification of CMSMs derived from this high-free-volume polymer precursor is thermodynamically driven by the collapse of large unconnected graphene domains to reach a more stable conformation (i.e., graphite). This study describes a novel strategy to mitigate phys. aging by pillaring the CMSM using copper nanoparticles. Highly soluble metal-organic polyhedra-18 (MOP-18) was introduced into PIM-1 with loadings up to 40 wt/wt to form a mixed-matrix membrane (MMM). Pyrolysis of the MMM at 550°C resulted in the in situ formation of copper metal nanoparticles that acted as pillars for the graphene sheets within the CMSM, preventing the collapse of the micropores, thus minimizing the aging of the CMSM. Single gas permeation measurements of CO₂ and CH₄ were made on the pristine polymer-derived CMSM and the copper-pillared CMSM at 35°C and 2 bar to confirm the membranes’ resistance to phys. aging. The CH₄ permeability for the PIM-1 CMSM decreased by ∼60%, from 64 to 27 Barrers, over a period of 7 days, while the copper-pillared PIM-1 CMSM remarkably showed essentially no decline in CH₄ permeability. This research demonstrates a general approach to reducing phys. aging in CMSMs.

Cottrez, Francoise;Leblanc, Virginie;Boitel, Elodie;Groux, Herve;Alepee, Nathalie research published 《 The EyeIRR-IS assay: Development and evaluation of an in vitro assay to measure the eye irritation sub-categorization of liquid chemicals》, the research content is summarized as follows. Several alternative methods have been developed and regulatory adopted by OECD as in vitro alternatives to the Draize eye irritation assay either to detect chems. not requiring classification (No Category) or inducing serious damage to the eye (Category 1) but none are sensitive enough to identify chems. inducing reversible eye effects (category 2) which are categorised by default. Therefore, the discriminatory power of a genomic approach applied to the SkinEthic Human Corneal Epithelium (HCE) model was investigated to allow subcategorization capacity according to UN GHS classification. An algorithm based on gene expression modulation on a training (62) and a test (31 liquids) chem. set, tested neat and at 30%was evaluated in an assay called EyeIRR-IS. Its accuracy prediction to distinguish Cat1/Cat2 from No Cat was 95% with a specificity of 89% and a sensitivity of 98%. For subcategorization into the 3 GHS classes the accuracy reached 84% with 94% Cat1, 67% Cat2 and 89% No Cat correctly predicted. No Cat.1 chems. were underestimated as neg. with a majority of misclassified Cat2 over predicted as Cat 1. In conclusion, the performance of the assay suggests its added value in a defined approach for liquids to replace the Draize assay.

The structure of SCPM-ball type CoPc was confirmed by FT-IR, MALDI-TOF-MS, UV and SEM. The conversion dependence of the exptl. activation energy was readily determined by an isoconversional method. So, the Flynn-Wall-Ozawa (FWO) and Kissinger-Akahira-Sunose (KAS) showed that the linear copolymer precursor’s activation energies were as average 128.7 kJ/mol and 124.0 kJ/mol and those of SCPM-ball type CoPc were average 161.9 kJ/mol and 153.8 kJ/mol, resp. Conductivity mechanism of composites was suggested as Correlated Barrier Hoping (CBH). The linear copolymer precursor/graphite oxide (GO) composite has a significant performance for dielec. constant of 696.4 at 130°C, but it was with a comparatively greater dielec. loss. Those of SCPM-ball type CoPc/14wt% GO increased virtually the same relative ratio.

Three new π-conjugated 4-(thieno[3,2-b]thiophen-3-yl)benzonitrile based monomers having thiophene, 3-hexylthiophene and EDOT at the peripherals were synthesized. Their electropolymerization produced the corresponding electroactive polymers, P1, P2, and P3, which exhibited electrochromic properties with color developments from red to blue, orange-yellow to pale-blue, and purple to pale-gray, resp. Functional design of the monomers with electron deficient benzonitrile at β-position of thieno[3,2-b]thiophene (TT) and electron-rich thienyl groups at the peripherals influenced the HOMO and LUMO levels and, thereby, reduced the band gap of the conjugated polymers. Considering the band gaps of electropolymerized TT based polymers in the literature, the polymer P3, obtained through electropolymerization, had a comparable band gap of 1.73 eV. Electrochromic devices (ECD) of the new polymers displayed different optical contrasts (ΔT%) of 20% at 507 nm, 25% at 443 nm, and 34% at 579 nm for P1/PProDOP, P2/PProDOP, and P3/PProDOP, resp.
