to form the ladder structure (Scheme 1). Both strategies can potentially lead to bran ching/crosslinking and/or introduce non - ladder structural defects, unless the chemistry and monomer structures can be elegantly designed to render highly (ideally exclusively) selective and efficient ladder formation. Scheme 1.

2020年4月24日 · Here, the authors minimize this confinement using a vertically-stacked fused aromatic ladder structure and demonstrate excellent gas uptake under low and high pressure. Planar two-dimensional (2D ...
