Abstract:
Environmentally stable novel flexible bisperylene resorcin[4]arene molecular switch cavitand B and the corresponding rigid cavitand A were synthesized and a single crystal was obtained. Spectroscopic analysis revealed the formation of an excimer of perylene within the cavitand. The presence of flexible chains in cavitand B confers a high degree of environmental stability, rendering its fluorescence unaffected by external factors such as pH and temperature variations. In contrast, the rigid cavitand A exhibits heightened sensitivity to changes in environmental conditions.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
