    A sequential Sonogashira cross-coupling/Pd-mediated oxidative homocoupling strategy affords two expanded dehydrobenzoannulene (DBA) structures containing two [14]DBAs fused to an [18]DBA core. Noticeable differences in the absorption and emission spectra are observed in comparison with a structurally related [18]DBA-centered trefoil containing three fused [14]DBAs.
