Abstract

Developing luminescent radicals with tunable emission is a challenging task due to the limitation of alternative skeletons. Herein, a series of carbene‐triphenylamine hybrids were prepared by the direct C2‐arylation of N‐heterocyclic carbenes with 4‐bromo‐N,N‐bis(4‐methoxyphenyl)aniline. These hybrids showed multiple redox‐active properties and could be converted to carbon‐centered luminescent radicals with blue‐to‐cyan emissions (λmax: 436–486 nm) or nitrogen‐centered luminescent radicals with orange emissions (λmax: 590–623 nm) through chemical reduction or oxidation, respectively. The radical species were characterized by electron paramagnetic resonance spectroscopy, ultraviolet‐visible spectroscopy, and single‐crystal X‐ray diffractometry analysis. Notably, the corresponding nitrogen‐centered radicals exhibited good stability in atmospheric air, and their thermal decomposition temperatures were determined to be above 200 °C. In addition, spectral and theoretical calculations indicate that all radicals exhibit anti‐Kasha emissions. [ABSTRACT FROM AUTHOR]

Abstract

Two undescribed phenylpropenoid glycosides (1 − 2) and one known analogues (3) have been isolated and identified from the roots of Illicium dunnianum. The structures of these new compounds were elucidated by extensive spectroscopic analyses (1 D-, 2 D-NMR, HRESIMS, IR, UV) and chemical methods. The anti-inflammatory activities of all isolates were evaluated by measuring their inhibitory effects on PGE2 production in LPS stimulated RAW 264.7 macrophages. [ABSTRACT FROM AUTHOR]

Abstract

The rapid development of advanced manufacturing technologies in micro-electro-mechanical system (MEMS) fields has promoted the advance in wearable electronics. Among them, wearable biomechanical micro-energy harvesters have attracted much attention in recent years to meet the unique power supply demands of wearable electronics serving as sustainable power sources. In the meanwhile, they also have been successfully demonstrated to be either self-powered sensors or other functional devices for wearable electronic applications. Herein, we overview the state-of-the-art of biomechanical micro-energy harvesters for wearable electronic applications, including the summary of working principles and structural configurations of biomechanical micro-energy harvesters. In detail, three promising technologies for biomechanical micro-energy harvesting are studied, i.e. electromagnetic effect, piezoelectric effect, and electrostatic effect. As for the structural configurations, two essential factors to affect the properties of biomechanical micro-energy harvesters are emphasized, i.e. new materials, and advanced manufacturing technologies. For wearable application scenarios, fiber/fabric-based materials and biodegradable/ecofriendly materials are investigated. For advanced manufacturing technologies, micro/nano fabrication technologies for precise fabrication and large-scale fabrication technologies for mass fabrication are summarized. Moreover, we review the wearable electronic applications of biomechanical micro-energy harvesters for powering, sensing, and actuating, respectively, which reveals the feasibility of constructing the smart wearable microsystems based on the abundant function of biomechanical micro-energy harvesters. Finally, we conclude the review and discussed the future development trends of biomechanical micro-energy harvesters for wearable electronic applications. [ABSTRACT FROM AUTHOR]
