Van der Waals (vdW) ferroelectrics have attracted significant attention for their potential in next-generation nano-electronics. Two-dimensional (2D) group-IV monochalcogenides emerged as a promising candidate due to strong room temperature in-plane polarization down monolayer limit. However, is strongly coupled with the lattice strain and stacking orders, which impact electronic properties. Here, we utilize four-dimensional scanning transmission electron microscopy (4D-STEM) simultaneously...
Two-dimensional (2D) films of conjugated porous organic polymers (C-POPs) can translate the rich in-plane functionalities frameworks into diverse optical and electronic applications while addressing processability issues their crystalline analogs for adaptable device architectures. However, lack facile single-step synthetic routes to obtain large-area high-quality 2D-C-POPs has limited application possibilities so far. Here, we report synthesis four mechanically robust imine-linked 2D-C-POP...
Abstract Structural design of 2D conjugated porous organic polymer films (2D CPOPs), by tuning linkage chemistries and pore sizes, provides great adaptability for various applications, including membrane separation. Here, four free‐standing CPOP imine‐ or hydrazone‐linked polymers (ILP/HLP) in combination with benzene (B‐ILP/HLP) triphenylbenzene (TPB‐ILP/HLP) aromatic cores are synthesized. The anisotropic disordered films, composed polymeric layered structures, can be exfoliated into...
Controlling the nanofiltration performance of chemically stable 2D conjugated porous organic polymer membranes with tunable pore architectures via functionalization, size and topology (homopore heteropore) modifications.
Two-dimensional (2D) DNA origami that is capable of self-assembling into complex 2D and 3D geometries pave the way for a bottom-up synthesis various applications in nano/biotechnology. Here, we directly visualized aqueous structure cross-tiles their assemblies using cryogenic electron microscopy. We uncovered flexible arms cross-tile monomers designated inter-tile folding. In addition, observed formation clusters stacks solution, which could potentially affect interaction assembly origami....
