Macrocyclic
10-mesityl-1,8-diphenylanthracene dimer 4 was synthesized
by using the electron-transfer oxidation of Lipshutz
cuprate derived from 1,8-bis(4-bromophenyl)-10-mesityl-anthracene 7 in moderate yield. This dimer 4 is a considerably
fluorescent molecule (ΦF 0.40) with high thermal,
photo, and air stability. The X-ray analysis of 4 revealed
a unique structure with a small inner cavity which can incorporate
a small molecule or atom. 1H NMR spectra in solution and
emission spectra of 4 in the solid state showed that
copper(I) ion was incorporated to form a 1:1 complex 4·CuOTf, whereas silver(I) ion only weakly interacted with 4 under similar conditions.
