Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A 1, 3‐phenylene‐bridged hexameric Zn^II porphyrin wheel was synthesized by a Suzuki–Miyaura coupling reaction through a one‐pot or a stepwise route. The hexameric wheel structure was revealed by using X‐ray diffraction analysis. The porphyrin wheel exhibits a split Soret band due to effective exciton coupling and displays efficient excitation energy transfer along the wheel. Measurements of fluorescence anisotropy decay and pump‐power‐dependent decay reveal a rapid excitation energy hopping along the wheel with a rate of 1.4 ps.</p> </abstract>
