A series of ethynylated silanes, including tetraethynylsilane was treated with tetraphenylcyclopentadienone at 300 8C under microwave irradiation to give the aromatized Diels-Alder adducts as sterically encumbered mini-dendrimers with up to 20 benzene rings. The sterically most congested adducts display red-shifted emission through intramolecular p-p interactions in the excited state.
