Neuromorphic computing systems, which mimic the neural architecture of the human brain, offer superior energy efficiency and processing speed compared to conventional von Neumann architectures, making them highly suitable for large-scale data processing [1]. A fundamental building block of these systems is the artificial synapse, which replicates synaptic plasticity—the dynamic modulation of synaptic strength in response to external stimuli. This adaptability is crucial for enabling neural networks to learn and retain information, supporting both short-term and long-term memory formation.
Organic memristors have emerged as promising candidates for flexible artificial synapses due to their mechanical compliance and capability to gradually modulate resistance states under electrical stimuli, effectively emulating synaptic plasticity [2]. Their functionality relies on the formation and dissolution of conductive filaments (CFs), allowing tunable synaptic weight modulation. However, practical implementation remains challenging, often necessitating intricate circuit designs and additional engineering considerations [3].
In this study, we introduce a small molecule-based organic memristor as a flexible artificial synapse, designed to precisely regulate CF growth pathways. This strategy enables selective emulation of both short-term and long-term plasticity, offering a versatile platform for implementing diverse neural network learning paradigms in flexible systems. The proposed approach is expected to enhance the learning and memory capabilities of artificial intelligence systems, contributing to the advancement of next-generation neuromorphic and wearable electronics.

nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
