三(苯基异恶唑基)苯1b与光化学可寻址偶氮苯基团的自组装形成环状纳米结构，其形成和解离受光照射的可逆调节。1B表现出介晶行为。在溶液中，堆积的组件和它们的C-3轴一起形成。在中期，1b的两个分子很可能采用反平行排列来稳定柱状组织。这种组装行为很可能引发了超分子环形纳米结构的发展。
The self-assembly of tris(phenylisoxazolyl)benzene 1b with photo chemically addressable azobenzene moieties produced toroidal nanostructures, the formation and dissociation of which were reversibly regulated upon photoirradiation. 1b displayed a mesogenic behavior. In the solution, the stacked assemblies along with their C-3 axes were formed. In the mesophase, two molecules of 1b most likely adopted the antiparallel arrangement to stabilize the columnar organization. This assembling behavior most likely triggered the development of the supramolecular toroidal nanostructures.
