Description

Since the introduction of metal-organic frameworks(MOFs), porous materials experienced a real
renaissance, simply because the concept of using oligotopic organic linker molecules coordinating to
metal ions or metal oxoion clusters allowed to exploit the chemical space by using an infinitesimal
number of possible organic linker molecules. However, MOFs as well as the covalent organic
frameworks (COFs) and other three-dimensional porous polymers have with zeolites and charcoals
in common that these are insoluble powders. Shape-persistent molecular organic cages have the
advantage that these are soluble and therefore more easy processable than the above mentioned
polymeric compounds. With specific surface areas of up to 3758 m2/g or high selectivities of gas
sorption compounds of this new type of porous materials are no longer exotic exceptions and can
compete with MOFs, COFs and zeolites for several applications. The development of this field from
the perspective of our laboratory is presented.
Another kind of porous organic molecules are the so called OMIMs (organic molecules of intrinsic
microporosity). These rely on frustrated packing. During our work on OMIMs we entered the field of
extended fused π-systems that are highly contorted, with exciting intrinsic properties. These systems
are discussed in the second part of the presentation.
