Round up : A fully conjugated cyclododeca‐2,7‐carbazole is prepared around a porphyrin template and the corresponding empty macrocycle then released. Single molecules could be visualized by STM (see image) and their arrangement by atomic force microscopy. The macrocycles self‐assemble into a hexagonal array of columns. Efficient energy transfer occurs from the peripheral carbazole π system to the central porphyrin core.
