“…Compared with other DCBs, the diselenide metathesis has a variety of advantages including rapid reaction rate, mild condition, and few by‐products 61. When introduced into material, the diselenide bond can be used for stress relaxation under visible light which endows materials with self‐healing,62 photo plasticity,63 3D topographical features,64 surface modification,65 etc. More importantly, the rate of diselenide metathesis could be adjusted by the wavelength of visible light 66.…”

Structural color materials with reversible stimuli‐responsiveness to external environment have been widely used in sensors, encryption, display, and other fields. Compared with other stimuli, visible light is highly controllable both temporally and spatially with less damage to materials, which is more suitable for structural color patterning. Herein, a new diselenide‐containing shape memory material is prepared and used for creating patterns via visible light stimulus. In this system, the structural color originates from birefringence of stretched materials, whose shapes can be fixed while maintaining the mechanical stress. The fixed stress can be released by diselenide metathesis under visible light irradiation. By regulating the wavelength or irradiation time with a commercial projector, the pattern with tunable structural colors is realized and the structural color pattern can be erased and rewritten arbitrarily. During the patterning process, the optical signal is first stored as mechanical signal and then transformed back to optical signal. It is a new method for preparing visible‐light‐responsive structural color material and has great potential in display devices, anticounterfeiting labels, and data storage.

“…Surface microstructures were produced as the result of differential swelling between the irradiated and nonirradiated regions. Beyond photodegradation, this swelling-induced photopatterning mechanism can also be achieved by the exchange reaction of dynamic covalent bonds . A diselenide cross-linked network was fully swollen in an organic solvent to form an organogel.…”

Dynamic Covalent Polymer Networks: A Molecular Platform for Designing Functions beyond Chemical Recycling and Self-Healing

Dynamic covalent polymer networks (DCPN) have historically attracted attention for their unique roles in chemical recycling and self-healing, which are both relevant for sustainable societal development. Efforts in these directions have intensified in the past decade with notable progress in newly discovered dynamic covalent chemistry, fundamental material concepts, and extension toward emerging applications including energy and electronic devices. Beyond that, the values of DCPN in discovering/designing functional properties not offered by classical thermoplastic and thermoset polymers have recently gained traction. In particular, the dynamic bond exchangeability of DCPN has shown unparalleled design versatility in various areas including shape-shifting materials/devices, artificial muscles, and microfabrication. Going beyond this basic bond exchangeability, various molecular mechanisms to manipulate network topologies (topological transformation) have led to opportunities to program polymers, with notable concepts such as living networks and topological isomerization. In this review, we provide an overview of the above progress with particular focuses on molecular design strategies for the exploitation of functional material properties. Based on this, we point out the remaining issues and offer perspectives on how this class of materials can shape the future in ways that are complementary with classical thermoplastic and thermoset polymers.

“…In addition, the reaction requires stringent conditions and involves volatile monomers. Dynamically cross-linked hydrogels and organogels can also alter their surface structures by adaptive swelling ( 15 , 16 ). However, the volatility of the solvent/water makes it difficult to control and intrinsically challenging for high-fidelity growth of microstructures.…”
