Unprecedented three-level hierarchical entanglement in a coordination polymerf

摘要

An unprecedented three-level hierarchical entangled system was synthesized. The basic helical ribbons of the complex were entangled into 2D layers by self-penetration based on 1D → 2D polyeatenation; a pair of layers interpenetrated, and crosslinked to construct the second self-penetrated bilayers which were further polycatenated into the final 3D entangled array.
