New class of hyperpolarizable push–pull organic chromophores by applying a novel and convenient synthetic strategy

• A novel class of push–pull chromophore has been reported using reverse synthetic strategy.
• Open a convenient way to high active electro optic organic chromophores.
• Synthesis of hyperpolarizable chromophores just in two steps.
• The advantages of this method are high atom economy, low-cost reagents, and mild reaction conditions.

A new class of push–pull chromophore with an azomethine unit at a key position of the chromophore in order to increase the hyperpolarizability is reported. Additionally, a novel and convenient synthesis method is introduced which is particularly advantageous compared with known procedures because it offers high atom economy, the use of low cost reagents, and mild reaction conditions together with a reduced number of reaction steps.
