Conjugated microporous networks on the basis of 2,3,5,6-tetraarylated diketopyrrolo[3,4-c]pyrrole.

ABSTRACT: π-Conjugated microporous networks have been prepared from the tetraarylated diketopyrrolo[3,4-c]pyrrole unit as a tetrafunctional building block. The reactions are carried out using microwave-assisted Yamamoto or Sonogashira cross-coupling. Red insoluble powders are obtained, showing intense fluorescence. The polymer networks exhibit a high gas storage capability, with BET surface areas up to about 500  m(2)·g(-1).
