摘要

研究了含萘-二亚胺（π-受体）和噻吩（π-供体）共轭发色团的双极性π-体系的氢键超分子组装及其热释电（PY）和光PY性质。最大PY系数为206µC m-2K-1 (at Tc)，光照射后的PY系数增加了几倍。高能量密度、功率密度和比例效率表明了该柔性传感器系统的有效性。

Electronic pyroelectricity in a supramolecular assembly of an acceptor–donor–acceptor-type ambipolar π-system†

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 T_c) 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.
