Electron-Transfer Photochromism To Switch Bulk Second-Order Nonlinear Optical Properties with High Contrast

The first bulk electron‐transfer photochromic compound with intrinsic second‐order nonlinear optical (NLO) photoswitching properties has been synthesized. This system employs an electron‐transfer photoactive asymmetric viologen ligand coordinated to a zinc(II) center. A light‐driven switch: A photoc...

Description
Summary:The first bulk electron‐transfer photochromic compound with intrinsic second‐order nonlinear optical (NLO) photoswitching properties has been synthesized. This system employs an electron‐transfer photoactive asymmetric viologen ligand coordinated to a zinc(II) center. A light‐driven switch: A photochromic zinc(II) compound, employing a photoactive asymmetric viologen ligand, exhibits electron‐transfer‐based photoswitching of bulk second‐order nonlinear optical properties (NLO) with high contrast.
