The synthesis of second-order nonlinear optical chromophores with conjugated steric hindrance for electro-optics at 850 nm

We show the strategy of introducing a suitable conjugated site-isolator on the bridge of a nonlinear optical chromophore to significantly improve the electro-optic activity at the shortwave infrared window (850 nm) for electro-optic modulation.

Structure–property analysis of julolidine-based nonlinear optical chromophores for the optimization of microscopic and macroscopic nonlinearity

A structure–property relation investigation revealed that the theoretical hyperpolarizability and experimental solvatochromism were more reliable in julolidine-based nonlinear optical chromophore design.

Synthesis and characterization of a novel indoline based nonlinear optical chromophore with excellent electro-optic activity and high thermal stability by modifying the π-conjugated bridges

Electro-optic activity and thermal stability are increased a lot after modifying the π-conjugated bridges via introducing suitable isolation groups.
