Abstract:
A triphenylamine-containing π-conjugated pillar[5]arene luminescent small organic molecule has been synthesized via Suzuki-coupling reaction. This molecule can self-assemble to form linear supramolecular polymers in both solution and solid state. The molecule shows enhanced emission compared with parent pillar[5]arene in dilute solution. Based on the bright luminescent behavior, its sensing ability for Cr2O7 2- anion was studied.

Selection Rules: Thermal Activation
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.
