- Abstract
We propose that a new and potentially extensive class of solid
polymeric materials with unprecedented and possibly useful
properties may be afforded by linking together centers with either a tetrahedral or an octahedral array of valencies by rod-like connecting units. For example, if ways could be devised of linking together tetrahedral centers and appropriate molecular rods, an infinite molecule would be generated which might be expected to adopt a structure based on either the cubic diamond lattice or the hexagonal Lonsdaleite lattice in which each C-C bond of the prototype had been replaced by a molecular rod. These frameworks would generate a regular array of cavities, interconnected by windows. When models of 3D networks based on tetrahedral centers are constructed, a very striking feature is the relatively large size of the cavities and windows produced even by rods of only modest length.
