A series of basket-shaped quinacridone (QA) cyclophanes 1–6 has been synthesized and characterized. Single-crystal X-ray analysis of 5 shows no infinite π–π aggregation between QA cores, reflecting a significant isolated effect of the bridging tethers. Photophysical properties have been carefully investigated. All cyclophanes show much higher quantum yields in concentrated solutions compared to the
