Controlled assembly of an unprecedented 2D + 3D interpenetrated array of (4,4)-connected and pcu topologies

We achieved the truly ‘engineered’ 2D + 3D interpenetrated array of (4,4)-connected + pcu nets. This fascinating interpenetrated array has remained unknown since its prediction was made about ten years ago. The successful construction was based on the introduction of a large flat anthracene group in the organic linker that effectively manipulates interpenetration.
