Outline of Final Research Achievements

Three novel supramolecular D-A nanocrystals, comprising fullerene and porphyrin were prepared by a simple liquid-liquid interfacial precipitation method and fully characterized by means of optical microscopy, AFM, STEM, TEM, and XRD. It is established that the highly crystalline fullerene/ porphyrin nanocrystals show n-type charge transport characteristics when incorporated in bottom-gate, bottom-contact field-effect transistors (FETs).
