The design and synthesis of nonlinear optical chromophores containing two short chromophores for an enhanced electro-optic activity

A series of nonlinear optical chromophores A–D based on the diethylaminophenyl donor and tricyanofuran or phenyl-trifluoromethyl-tricyanofuran acceptors coupled through a tetraene bridge was synthesized and investigated.

Synthesis of nonlinear optical chromophores with isophorone-derived bridges for enhanced thermal stability and electro-optic activity

In this work, we developed a series of nonlinear optical chromophores J1–J4 with the same julolidinyl-based donor and tricyanovinyldihydrofuran acceptor with different modified isophorone-derived bridges.

A TCBD-based AB2-type second-order nonlinear optical hyperbranched polymer prepared by a facile click-type postfunctionalization

A double click-type postfunctionalization strategy was successfully designed to prepare an AB2-type hyperbranched polymer containing highly polarizable tetracyanobutadienyl (TCBD)-based nonlinear optical chromophores.

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.
