New conjugated macrocycles consisting of tricoordinate boron units and dithienogermole (DTG) were prepared by Stille cross‐coupling reactions. The element‐hybrid macrocycles exhibited energy transfer from the DTG units to the macrocyclic backbone in the fluorescence spectra. In the fluoride titration experiments, clear turn‐on and turn‐off fluorescence responses were observed for different conjugated linkers. For more information, see the Full Paper by F. Jäkle and J. Ohshita et al. on page 3306.
