Molecular Engineering for Enhanced Second‐Order Nonlinear Response in Spontaneously‐Oriented Evaporated Organic Films

Advanced Optical Materials, EarlyView.
Intramolecular bridge‐locking frustrates detrimental anti‐parallel packing in evaporated organic films. This design enhances net polar orientation, leading to a twofold off‐resonance increase in the second‐order nonlinear susceptibility (χ(2)) without electric‐field poling.
