“…In our previous work, the strong chelating effect between Pb 2+ ion and oxygen achieves the excellent anti-solvent feature of PS-b-PEO/2D OIHP composite film that enable solution processable P3HT as a charge-transporting channel. [1,4,40] Figure S1a,b, Supporting Information, presents the transmission electron microscopy (TEM) imagines of the BCP/(PEA) 2 PbBr 4 and BCP/(BPMA) 2 PbBr 4 composite films, respectively. The dark regions can be assigned to the PEO/2D OHIP domains which leads the PS cylinders well-distributed in both BCP/2D OHIP composite films.…”

Room‐temperature phosphorescence (RTP) two‐dimensional (2D) organic‐inorganic hybrid perovskites (OIHPs) that possess superior stability and efficient triplet energy transfer between inorganic parts and organic cations have been seen as promising materials in optoelectronic devices. However, the development of RTP 2D OIHP‐based photomemory has not been explored yet. In this work, the spatially addressable RTP 2D OIHPs‐based nonvolatile flash photomemory is first investigated to explore the function of triplet excitons in elevating the performance of photomemory. Thanks to the triplet excitons generated in RTP 2D OIHP, extremely low photo‐programming time of 0.7 ms, multilevel behavior of minimum 7 bits (128 levels), remarkable photoresponsivity of 19.10 AW−1 and significantly low power consumption of 6.79 × 10−8 J per bit can be achieved. The current study provides a new prospective in understanding triplet excitons function in nonvolatile photomemory.

“…2022, 32, 2206040 the brain is seen as a highly attractive topic for the application of in-memory computing. [56][57][58][59][60][61] The behavior of floating-gate photomemory actually is similar to the synaptic transmission process, where the transmission will take place as there is an action potential triggered by a light signal. When the light signal is received, the neurotransmitter will be released from the pre-synaptic neuron, cross the synaptic cleft, and then received by the post-synaptic neuron.…”

Phosphorescent materials have received considerable attention in organic solar cells (OSCs) due to their long emission lifetime and inhibited geminate recombination. Motivated by its particular photophysical property, herein, the spatially addressable bis(2‐benzo[b]thiophen‐2‐ylpyridine)(acetylacetonate)iridium(III) (Ir(bt)2(acac))/polystyrene‐b‐poly(4‐vinylpyridine) (PS‐b‐P4VP) as a photoactive floating‐gate is first demonstrated to explore the application of phosphorescent material on the photo‐responsive characteristics of photomemory and artificial photonic synapse. By manipulating the interfacial area between Ir(bt)2(acac)/PS‐b‐P4VP and active channel by a solvent annealing process, an ON/OFF current ratio of 103 and a low programming time of 700 ms can be achieved. The current study addresses the exciton lifetime of photoactive material functions in photomemory and highlights the interfacial area between photoactive materials and charge‐carrier transporting materials in reducing photo‐programming time.

“…However, the human brain will process information with low power consumption owing to inherent analog capability and efficient parallel connection. [ 120 ] Brain‐inspired computing chips provide an energy efficient approach for new chip architectures and device technologies. Each neuron is interconnected by more than 10 000 synapses in human brains responsible for receiving and transmitting signals to other neurons.…”

Ferroelectric materials with switchable electrical polarization have been widely used in tunnel junctions, non-volatile memories, and field-effect transistors. Large-area organic ferroelectric polymers compatible with silicon or flexible substrates have played a crucial role in nanoelectronics. Poly(vinylidene fluoride-trifluoroethylene) P(VDF-TrFE) as a representative, different from traditional bulk oxide ferroelectrics in terms of atom arrangements and fabrication methods, has frequently been used as the ferroelectric gate for high-performance electronic, optical, and synaptic transistors. Ferroelectric copolymers have gradually become a promising and versatile alternative for inorganic ferroelectrics. This review will focus on the interface engineering and device applications of 2D materials/ferroelectric P(VDF-TrFE) hybrid structures. The intrinsic ferroelectric properties and unique features of P(VDF-TrFE) are first elucidated. Next, typical device structures with ferroelectric gating effect followed by its physical working mechanisms will be discussed. In the next section, diverse nanoelectronics applications of ferroelectric field effect transistors based on P(VDF-TrFE), including optoelectronic devices, non-volatile memories, neuromorphic computing, and negative capacitance transistors, are clarified. Moreover, existing challenges and further development for ferroelectric polymer will be discussed. With an emphasis on the ferroelectric polymer gate and related issues, this review provides a timely summary of current physical understanding and progresses.
