Abstract:
Hydrogen-bonded supramolecular assembly of an acceptor-donor-acceptor (ADA)-type ambipolar π-system containing naphthalene-diimide (π-acceptor) and thiophene (π-donor) conjugated chromophores is examined for promising pyroelectric (PY) and photo-PY properties. A maximum PY coefficient of ∼206 μC m-2 K-1 (at Tc) and multifold enhancement after light irradiation is reported. High energy density, power density and scaled efficiency indicate the efficacy of such a nontrivial system for flexible sensors.

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.
