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.
