5-(4-Ethoxyphenyldiazenyl)-8-hydroxyquinoline

Acta Crystallographica Section E Structure Reports Online, 2006
In the mol­ecules of the title compound, C17H15N3O2, the ethoxy­phenyl ring forms a dihedral angle of 7.37 (11)° with the quinoline ring system. In the crystal structure, inter­molecular O—H⋯N hydrogen bonds link the mol­ecules into centrosymmetric R22(10) dimers; these dimers are arranged in sheets parallel to the ab plane.

No Charging but Protection: Lifetime Prolongation of Spontaneously‐polarized Electrets for Energy Harvesting Applications

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A bilayer protection approach is proposed for slowing down the surface potential decay of thin films of spontaneously‐polarized electret materials. The electret and the protective films are characterized, and the protection effectiveness is investigated under the effects of light illumination, water contact and mechanical impact.
