“…Compared to inorganic materials, organic semiconductor materials are considered the most ideal materials for constructing neuromorphic devices due to their ease of processing at low temperatures. [11][12][13][14][15] In addition, Organic materials offer a wide variety of options, easy regulation of molecular structure, low power consumption, and sufficient stability. 9,[16][17][18][19][20][21] 6,13-bis (triisopropylsilylethynyl) pentacene (TIPS-pentacene), as a P-type small molecule organic material, has excellent semiconductor properties and photoelectric properties.…”

Biological learning and memory of visual information are carried out through the regulation of synaptic weight by visual neuron synapses. Replicating the cognitive processes and light-induced adaptability of the human brain holds immense significance for the advancement of artificial intelli-gence. Here, we propose an organic photoelectric synaptic transistor based on 6,13-bis(triisopropylsilylethynyl) pentacene (TIPS-pentacene). The device showcases a memory win-dow greater than 20 V and current on/off ratio of 106. Synaptic behavior transition is exhibited from short-term plasticity (STP) to long-term plasticity (LTP) under photoelectric pulse modulation, in-cluding paired-pulse facilitation (PPF), spike time dependent plasticity (STDP), spike number de-pendent plasticity (SNDP) and optical enhancement/electrical inhibition. In addition, we simulate the learning and adaptation process of the synaptic device after long-term light stimulation, and recognize visual information by perceiving light pulses in different time domains.

“…Organic-inorganic hybrid materials are a new field of composite materials that combine many excellent properties of organic and inorganic materials, such as the low density, good viscoelasticity, high toughness, and good processability of organic materials, and the high hardness, high modulus of elasticity, high strength, better light transmission, and high refractive index of inorganic materials [ 10 , 11 , 12 , 13 ]. Organic-inorganic hybrid membrane materials combine the excellent properties of both organic and inorganic components, and their rapid development provides new ideas for the design and development of membrane materials [ 14 , 15 , 16 , 17 , 18 ].…”

A series of hybridized charged membrane materials containing carboxyl and silyl groups were prepared via the epoxy ring-opening reaction and sol–gel methods using 3-glycidoxypropyltrimethoxysilane (WD-60) and polyethylene glycol 6000 (PEG-6000) as raw materials and DMF as a solvent. Scanning electron microscopy (SEM), fourier transform infrared spectroscopy (FTIR), and thermal gravimetric analyzer/differential scanning calorimetry (TGA/DSC) analysis showed that the heat resistance of the polymerized materials could reach over 300 °C after hybridization. A comparison of the results of heavy metal lead and copper ions’ adsorption tests on the materials at different times, temperatures, pHs, and concentrations showed that the hybridized membrane materials have good adsorption effects on heavy metals and better adsorption effects on lead ions. The maximum capacity obtained from optimized conditions for Cu2+ and Pb2+ ions were 0.331 and 5.012 mmol/g. The experiments proved that this material is indeed a new environmentally friendly, energy-saving, high-efficiency material. Moreover, their adsorptions for Cu2+ and Pb2+ ions will be evaluated as a model for the separation and recovery of heavy metal ions from wastewater.

“…Inorganic semiconductors, such as TiO 2 , ZnO, CdS, ZnSe, ZnS, and WO 3 , have been extensively studied during the last decade for multiple applications in the field of science and technology. [1][2][3][4][5][6][7][8] Among these semiconductors, ZnO with its fascinating properties and plethora of applications has attracted more use in the semiconductor field. ZnO is stable, nontoxic, and exhibits specific properties such as high electron mobility, good transparency, high room temperature luminescence, large exciton binding energy (60 meV) and wide bandgap (3.37 eV) [9][10][11][12][13][14] and was selected for the present study.…”

In the present article we report the synthesis of zinc oxide (ZnO) nanostructures at room temperature using an ultrasonication technique to study their photoluminescent and photocatalytic behaviour. Synthesized nanomaterial showed a strong near band edge ultraviolet (UV) light emission and red emission, thereby finding its use in photoluminescent materials. We developed a UV/ZnO/O2/H2O2 system for the photodegradation of organic pollutants in an aqueous system. We used synthesized nanostructures to photodegrade phenol red (PR) dye to check their photocatalytic activity. The ZnO nanostructures photodegraded more than 90% of the PR dye under UV light irradiation in which photonic energy is converted to chemical energy (photocatalytic energy conversion), thereby exploitable for water purification applications. Synthesized ZnO nanostructures were characterized using powder X‐ray diffraction, Fourier transform infrared spectroscopy, UV–visible light spectroscopy, scanning electron microscopy, and energy dispersive X‐ray spectroscopy to investigate their structural, optical, morphological, and compositional properties, respectively.
