in the solvent polarity. Both 1 and 2 underwent intramolecular [4+4] cycloaddition. The quantum yield of the cyclomerization of 1 was 0.24 in acidic methanol, while in MeCN the reaction was completely quenched by an intramolecular electron transfer from the amino group to the excited anthracene moiety. Excitation of the cyclomer from 1 at 285 nm brought about fluorescene from both the locally excited
