Linking of molecular building blocks into predetermined structures that are held together by strong bonds (reticular chemistry) has resulted in a new class of crystalline metal-organic frameworks; members of which are now being scaled up and marketed by BASF in ‘drop-in' technologies. In our efforts to develop other new classes of materials, we have recently succeeded in applying reticular chemistry design principles to making covalent organic frameworks (COFs) and zeolite imidazolate frameworks (ZIFs). In the spirit of this symposium, honoring a scientist who has broken many records in the design of useful molecules, we report on our most latest results and the breaking of three records: (1) the design of zeolite tetrahedral structures that are entirely composed of transition metals and imidazolate links, (2) crystals with the largest unit cell dimensions ever reported in Cambridge Structure Database, and (3) the least dense crystals known to mankind. The chemistry of these new materials and their applications will be discussed.
