Neuromorphic computing has been extensively studied to mimic the brain functions of perception, learning, and memory because it may overcome the von Neumann bottleneck. Here, with the light‐induced bidirectional photoresponse of the proposed Bi2O2Se/graphene hybrid structure, its potential use in next‐generation neuromorphic hardware is examined with three distinct optoelectronic applications. First, a photodetector based on a Bi2O2Se/graphene hybrid structure presents positive and negative photoresponsibility of 88 and −110 A W−1 achieved by the excitation of visible wavelength and ultraviolet wavelength light at intensities of 1.2 and 0.3 mW cm−2, respectively. Second, this unique photoresponse contributes to the realization of all optically stimulated long‐term potentiation or long‐term depression to mimic synaptic short‐term plasticity and long‐term plasticity, which are attributed to the combined effect of photoconductivity, bolometric, and photoinduced desorption. Third, the devices are applied to perform digital logic functions, such as “AND” and “OR,” using full light modulation. The proposed Bi2O2Se/graphene‐based optoelectronic device represents an innovative and efficient building block for the development of future multifunctional artificial neuromorphic systems.

A catalytic protocol for "CF 3 "-radical type addition to terminal and β-substituted olefins with Togni's reagent to deliver various αtrifluoromethylated ketones of biomedicinal interests was examined by a series of oxovanadium species under oxygen atmosphere at ambient temperature. Among six different V(O)X 2 bearing (bi)pyridine, imidazole, and (bis)oxazoline ligands and five different oxidovanadium complexes derived from N-salicylidene tert-leucinate, and salen ligands examined, the complexes with 3,5-dibromo substituents and VO(OTf) 2 with bisoxazoline type ligands led to the best results.
