Article Abstract
A robust single-molecule memristor is prepared by covalently integrating one phenol molecule with multiple binding sites into nanogapped graphene electrodes. Multilevel resistance switching is realized by the electric-field-manipulated reconfiguration of the acyl moiety on the phenol center, that is, the Fries rearrangement. In situ measurements of the reaction trajectories with an initial single substrate and an intermediate break through the limitation of macroscopic experiments, therefore unveiling both intramolecular and intermolecular mechanistic pathways (a long-term controversy) as well as comprehensive dynamic information. Based on this advance, high-performance single-molecule memristors in both the solution and solid states are achieved successively, providing a new understanding of memristive systems and neural network computing.

Single-molecule junctions (SMJs) were fabricated incorporating photochromic diarylethene units, which are covalently bonded to a bottom electrode by diazonium electro-reduction. The scanning-tunneling-microscopy break-junction (STM-BJ) and conductance versus time (STM-()) techniques characterize the different conductance states upon light irradiation, whereas the STM current versus voltage (/) measurement at room temperature allows electric-field-stimulated conductance switching. We observe that the Au-[DAE]-Pt SMJs appear with a single conductance state.

Solid-state nanopores are a key platform for single-molecule detection and analysis that allow engineering of their properties by controlling size, shape, and chemical functionalization. However, approaches relying on polymers have limits for what concerns hardness, robustness, durability, and refractive index. Nanopores made of oxides with high dielectric constant would overcome such limits and have the potential to extend the suitability of solid-state nanopores toward optoelectronic technologies.

In the big data era, the requirement for data clustering methods that can handle massive and heterogeneous datasets with varying distributions increases. This study proposes a clustering algorithm for data sets with heterogeneous density using a dual-mode memristor crossbar array for data clustering. The array consists of a Ta/HfO/RuO memristor operating in analog or digital modes, controlled by the reset voltage.

Voltage-gated processing units are fundamental components for non-von Neumann architectures like memristor and electric synapses, on which nanoscale molecular electronics have possessed great potentials. Here, tailored foldamers with furan‒benzene stacking (f-Fu) and thiophene‒benzene stacking (f-Th) are designed to decipher electro-responsive through-space interaction, which achieve volatile memory behaviors via quantum interference switching in single-molecule junctions. f-Fu exhibits volatile turn-on feature while f-Th performs stochastic turn-off feature with low voltages as 0.
