Current nonlinear optical materials face a conventional limitation in the trade‐off between the band gap and birefringence, especially in the deep UV spectral region. To circumvent this dilemma, we propose a general principle, π‐conjugated confinement, to partially decouple the interunit π‐conjugate...
