Tremendous efforts have been devoted to wearable mechanical sensors to meet growing needs in healthcare sensors and electronic skins.

In this review, the state-of-the-art advances in amorphous carbon materials of the daily carbon ink for pressure, strain, and humidity sensors are presented and discussed.

Flexible optoelectronics have attracted much attention in recent years for their potential applications in healthcare and wearable devices.

For the first time, Cs₄MnBi₂Cl₁₂ single crystals were employed for photocatalytic degradation of organic pollutants. Joint experiment–theory characterizations reveal the good stability, high recovery and utilization rates of Cs₄MnBi₂Cl₁₂.

Circularly polarized luminescent chiral organogels based on fluorescence resonance energy transfer are fabricated by supramolecular co-assembly in an achiral polymer system, in which a wavelength shift and amplified g_lum are achieved.

A multifunctional vertical organic phototransistor for smart optoelectronic applications has been demonstrated by precisely engineering the current path.

The p–n junction, one of the prominent electrical components capable of being utilized in electronics and optoelectronics, has attracted renewed interest due to recent research in two-dimensional (2D) materials.

Hybrid organic–inorganic materials offer an alternative to state-of-the-art Pb-based piezoelectric materials. Here, we develop a model Hamiltonian including vibrational entropic contributions to simulate their order–disorder phase transitions.

Cs₂ZnBr₄:Mn²⁺ and its composite film demonstrate good X-ray scintillation performances with a spatial resolution of 5.06 lp mm⁻¹ in X-ray imaging.

The isomerism effect on the aggregate emission properties of perylene diimide derivatives is studied. Banking on their bright emission, a cellular imaging test based on their nanoparticles is also conducted.

The impact of Ag interlayer formation governing the intrinsic mechanical behavior of ITO/Ag/ITO thin films is proposed, which can fundamentally contribute to the robust design of advanced flexible electronics.

Near-infrared emission was achieved via the intermolecular through-space electronic coupling and intramolecular charge transfer.

Efficient tunable emission in (C₁₃H₃₀N)₂SnCl₆:Sb can be applied in WLEDs, information encryption, etc., which originates from DAP transitions, and SbCl₆, and SbCl₅ clusters in crystals.

Four bipolar host materials, namely MS-CN, MS-OC, MS-PC, and MS-TPA were designed, synthesized, and their photophysical and electrochemical studies were investigated.

An inorganic/organic CABB/Ni-MOF hybrid photocatalyst was fabricated. Due to the efficient charge separation, high reduction potential preservation, and the improved CO₂ adsorption, the CABB/Ni-MOF hybrid showed high CO₂ photoreduction activity.

In this study, it was theoretically demonstrated that efficient intrachain energy transfer and robust network structure construction improved the UV resistance of the epoxy matrix.

A CsCu₂I₃ SA-based passively mode-locking fiber laser was demonstrated. The fiber laser could operate stably for at least five months, which will potentially unlock the pathways for ultrafast photonics based on lead-free halide perovskites.

A HfO₂ film was grown using discrete feeding ALD, an advanced ALD process designed to improve the surface coverage of the precursor, which decreased the residual impurities in the film and increased the film density.

Solution-processed light-emitting device was feasibly achieved by a new exciplex-forming BCz3Ph : PO-T2T blend as the emitting layer casted on top of a thermally polymerized hole-transporting layer formed by a dicarbazole-based monomer BCzC4Sy.
