Coordination-Mode-Modulated Symmetry Breaking for Nonlinear Optical Crystals.
Second-order nonlinear optical crystals are essential to photonics but face the challenge of combining large nonlinearity, high laser damage threshold, and suitable birefringence. We address this via a "multi-coordination-site-induced" strategy in metal complexes, employing d10 Cd2+ to induce second-order Jahn-Teller d...
