A stiff and healable polymer is obtained by using the dynamic-covalent boroxine bond to crosslink PDMS chain into 3D networks. The as-prepared very strong stiff, can bear a load of more than 450 times its weight. When damaged, it be completely healed upon heating after wetting.

Abstract There is often a trade-off between mechanical properties (modulus and toughness) dynamic self-healing. Here we report the design synthesis of polymer containing thermodynamically stable whilst kinetically labile coordination complex to address this conundrum. The Zn-Hbimcp (Hbimcp = 2,6-bis((imino)methyl)-4-chlorophenol) bond used in work has relatively large association constant (2.2 × 10 11 ) but also undergoes fast reversible intra- inter-molecular ligand exchange processes....

A new self-healing polymer has been obtained by incorporating a cyclometalated platinum(II) complex Pt(C∧ N∧ N)Cl (C∧ N = 6-phenyl-2,2'-bipyridyl) into polydimethylsiloxane (PDMS) backbone. The molecular interactions (a combination of Pt···Pt and π-π interactions) between complexes are strong enough to crosslink the linear PDMS chains an elastic film. as prepared can be stretched over 20 times its original length. When damaged, healed at room temperature without any healants or external...

Chemical systems with external control capability and self-recoverability are promising since they can avoid additional chemical or energy imposition during the working process. However, it remains challenging to employ such a nonequilibrium method for engineering of optoelectronic function visualization. Here, we report functional molecule that undergo intense conformational regulation upon photoexcitation. It enables dynamical change in hydrophobicity follow-up molecular aggregation...

It has emerged as leading technology for converting into electricity. demand self‐powered wearable microelectronics generation in extreme conditions underscores the need efficient high‐temperature operatable TENGs (HTO‐TENGs). However, operating environment temperature not only affects storage dissipation of electrons during triboelectrification, decreased output...

Cobalt(<sc>ii</sc>) triazole complexes were incorporated into a polydimethylsiloxane (PDMS) matrix. The resulting polymers show solvent-induced chromic behaviour as well self-healing properties.

Combining stretchability and self-healing properties in a man-made material is challenging task. For an efficient material, weaker dynamic or reversible bonds should be presented as crosslinks so that they will first break upon damage then reform after healing, which not favorable when developing elastic materials. In this work, by incorporating Fe(III)-triazole coordination into polydimethylsiloxane (PDMS) backbone, highly polymer obtained can thermally healed at mild temperature. The...

Circularly polarized luminescence (CPL) has attracted great interest owing to its extensive optical information and chiral structural dependence. However, rationally regulating solid-phase CPL signals remains difficult because of the close packing molecules in solid-state materials lack visualization. In this work, we proposed a microphase-separation-recognized regulation strategy via coassembly hexathiobenzene-based luminophore block copolymer (cBCP) with situ photocontrollability. As...

ConspectusIn the field of molecular assembly, photodriven self-assembly is a smart and crucial strategy to regulate orderliness, multiscale structure, optoelectronic properties. Traditionally, based on photochemical processes, through structural change induced by photoreactions. Despite great progress in self-assembly, there still exists disadvantages (e.g., photoconversion rate never reaches 100% with possible side reactions). Therefore, photoinduced nanostructure morphology are often...

Benefiting from the associative exchange reaction, vitrimers could be deformed to various shapes while maintaining integrity of network, thus being regarded as promising candidates for shape memory polymers. However, it is still a challenge design highly desired smart electronic devices with triple and multishape performances through facile method.

Controllable aggregation-induced emission luminogens (AIEgens) by photoexcitation can be conducted within a single solvent, thus opening new opportunities for preparing and processing smart materials. However, undesired side-reactions like photooxidation that easily occur in the organic phase remain, limiting their applications. To enhance operability of photoexcitation-controlled AIEgens (to specifically produce phosphorescence characteristic) phase, this work, we employ typical prototype,...

Via external stimuli such as CH3OH, H+, Ag+, HPTB's luminogenic character transitioned from blue fluorescence to green, yellow, orange phosphorescence. Results showed that this interconversion was a reversible process also reproducible in liquid the solid state.
