“…ROMP has been used to synthesize a variety of functional polymers/copolymers with tailored architectures and regulable properties. [59][60][61] Here, we adopted ROMP to prepare the Fc-and aldehyde-containing amphiphilic terpolymers P(NTEG x -NCHO y -NFc z ) (see Figure 1). As shown in Figure 1, the ROMP of three monomers (including NTEG, NCHO, and NFc) using Grubbs' 3rd generation catalyst could lead to the formation of the amphiphilic terpolymers P(NTEG x -NCHO y -NFc z ) with the dendritic oligoethylene glycol (OEG), aldehyde, and Fc moieties in the side chains.…”

Multifunctional hydrogels with good stretchability and self-healing properties have attracted considerable attention in the field of flexible electronic devices. However, hydrogels constructed by traditional chemical crosslinking usually have poor mechanical properties and lack self-healing, adhesion, and biocompatibility, which cannot meet the requirements of flexible wearable devices. This work introduced multiple dynamic crosslinking, including borate ester bond, Schiff-base, and host-guest interaction, into polymer networks to fabricate triple-network gelatin/polyvinyl alcohol/carbon nanotube composite hydrogels with good self-healing ability (healing efficiency of 95.0%), mechanical strength (54.6 kPa), stretchability (778%), biocompatibility, conductivity, adhesion, and remodeling properties. Carbon nanotubes can serve as the filler to improve the electrical conductivity of the triple-network hydrogels. The resulting hydrogel can be made into a strain sensor with high strain sensitivity (gauge factor up to 16.0). More importantly, the strain sensor can be used to monitor various human and organ movements. Owing to its good self-healing ability, the self-healed hydrogel sensor also can detect human movements with almost the same electrical signal strength as the original one. This study gives novel insights for the design of multifunctional self-healing hydrogels that have great potential in various application fields such as electronic skins, soft robots, and wearable devices.

“…[ 12 ] The strong electron‐donating component, affected by chemical or physical interactions at the interfaces, acts as an electron reservoir to store and transfer electrons, which plays a vital role in electron density and thus boosts electrocatalytic performance. [ 13 ] Encouraged by the catalytic activity and electron reservoir ability originating from heterostructure, the synergistic effect of both can absolutely achieve high‐electrocatalytic performance, yet remains unexplored.…”

Nanoscale Double‐Heterojunctional Electrocatalyst for Hydrogen Evolution

et al. 2022

The active sites and charge/mass transfer properties in electrocatalysts play vital roles in kinetics and thermodynamics of electrocatalysis, and impose direct impacts on electrocatalytic performance, which cannot be achieved by a simplex structure. As a prototype, the authors propose a double-heterojunctional nanostructure of NiS 2 /Ni 3 C@C containing NiS 2 /Ni 3 C and Ni 3 C/C heterojunctions as a general model to optimize the above issues and boost electrocatalytic performance. During the thermal reorganization, the in situ reaction between NiS 2 nanoparticles and carbon induces the formation of Ni 3 C between them and constructs tightly contacted two kinds of interfaces among the three components. The TEM and XPS reveal the intimately contacted three components and the as-constructed interacted dual interfaces, further confirming the formation of a porous double-heterojunctional nanostructure. Theoretical calculations uncover that the electron density redistribution occurs at Ni 3 C/C interface by spontaneous electron transfer from defected carbon to Ni 3 C and lower 𝚫G H* achieves at NiS 2 /Ni 3 C interface by the concentrated interfacial charge density, which favors the simultaneous realization of high catalytic activity and rapid charge/mass transfer. When applied for hydrogen evolution reaction (HER), the porous double-heterojunctional NiS 2 /Ni 3 C@C exhibits excellent HER activity and durability among all pH values. Profoundly, this special double-heterojunctional structure can provide a new model for high-performance electrocatalysts and beyond.

Development and Characterisation of Highly Conjugated Functionalised Ferrocenylene Macrocycles

2022

Multiple synthetic pathways were explored for the preparation of ethynylarene-containing ferrocenylene macrocyles. Accordingly, the synthesis of novel bis-and tris-ferrocenylene macrocycles, containing a diethynylpyridine bridging group was achieved, and evidence is also provided for a number of linearanalogues formed as by-products. The electrochemical properties of the macrocycles were examined, and it was shown that the number of observable redox processes does not necessarily correlate with the number of redox active centres. Additionally, examination of the comproportionation constants of the trisferrocenylene macrocycle demonstrated that the monocationic and dicationic species could be assigned to class II and I/II borderline of the Robin-Day classification, respectively. The synthesis of these molecules presents an opportunity towards the development of conjugated ferrocenylene macrocycles for electronic applications.
