Poly(isobutylene) (PIB) chains with a radical at the chain end were graftcopolymerized on the poly(tetrafluoroethylene) (PTFE) surface in vacuo at 77 K. The PIB chains tethered on the PTFE surface in vacuo were regarded as isolated chains from neighboring tethered PIB chains. The molecular motion of
Ο-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 flu
