Herein, the design of conjugated acetylenic polymers (CAPs) featuring diverse spatial arrangements and intramolecular spacers of diacetylene moieties (─C≡C─C≡C─) for photocatalytic hydrogen peroxide (H2O2) production from water and O2, without the need for sacrificial agents, is presented. It is shown that the linear configuration of diacetylene moieties within conjugated acetylenic polymers (CAPs)...
Hydrogen Peroxide Generation
In article number 2305004, Tao Zeng and co‐workers have designed three conjugated acetylenic polymers (CAPs) with linear or cross‐linked configurations for the photocatalytic production of H2O2, by manipulating the spatial arrangement and intramolecular spacer of the diacetylene moiety within CAPs. The optimized LCAP‐2 exhibited an impressive H2O2 production rate, attributed...
Neuromorphic Imaging Systems
In article number 2206181, Xiaoli Zhao, Qingxin Tang, and co‐workers present a multimodal‐synergistic‐modulation neuromorphic imaging systems based on ultraflexible synaptic transistors. The device is capable to simulate the spherical structure and the environmental adaptive behavior of the human eye. Based on the function that synaptic weight can be synergistically regulated...
Inspired by human eyes, the neuromorphic visual system employs a highly efficient imaging and recognition process, which offers tremendous advantages in image acquisition, data pre‐processing, and dynamic storage. However, it is still an enormous challenge to simultaneously simulate the structure, function, and environmental adaptive behavior of the human eye based on one device. Here, a multimodal‐synergistic‐modulation...
In article number 2006662, Zhongqiang Wang, Haiyang Xu, Guangshan Zhu, and co‐workers report a zeolite‐based memristive synapse with an ultralow energy consumption of sub‐10 fJ per synaptic spike. Several essential synaptic learning and memory functions are demonstrated in such zeolite‐based memristive synapse by electrical and chemical methods, which facilitates the development of highly efficient...
The development of neuromorphic computation faces the appreciable challenge of implementing hardware with energy consumption on the level of a femtojoule per synaptic event to be comparable with the energy consumption of human brain. Controllable ultrathin conductive filaments are needed to achieve such extremely low energy consumption in memristive synapses but their formation is difficult to control...
Organic luminogens constitute promising prototypes for various optoelectronic applications. Since gaining distinct color emissions normally requires the alternation of the conjugated backbone, big issues remain in material synthetic cost and skeleton compatibility while pursuing full‐color luminescence. Upon a facile one‐step coupling, three simple but smart perchalcogenated (O, S, and Se) arenes...
