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-2K-1 (at Tc) and multifold enhancement after light irradiation is reported. High energy density, power density and scaled efficiency indicate efficacy of such a nontrivial system for flexible sensors.
