By changing the position of the homochiral alkoxy substituents of C 3 ‐symmetric 1,3,5‐trialkynylbenzenes from the center to the periphery, the macroscopic chirality of the resulting aggregates (crystals or fibers), studied by various spectroscopic and microscopic techniques, was inverted, as confirmed by single‐crystal X‐ray diffraction analysis.
