Key words

polycyclic aromatic - hexabenzocoronene - optical property

Significance

Nanosized molecules bearing mono-, bis-, and tris(hexa-peri-hexabenzocoronene) group(s) (HBC) were prepared from truxene derivatives (R = hexyl) via Sonogashira coupling and decarbonylative Diels-Alder reaction followed by the oxidation with FeCl3 (preparation of trisHBC­ derivative is shown above).

Comment

The structural analysis and the optical properties of the star shaped aromatics were performed with MALDI-TOF, UV-Vis and other methods.
