An approach to the synthesis of α-cyanostilbazole derivatives based on the heterocyclization of tetracyanopropenides
The synthesis of α-cyanostilbazole derivatives via the heterocyclization reaction of arylmethylidene derivatives of the malononitrile trimer (YMNT-) is described. This approach opens up the possibility for the one step synthesis of α-cyanostilbazole derivatives with a highly functionalized pyridine fragment. The spectral-luminescent properties in solution as well as in the solid state were investigated. The obtained α-cyanostilbazoles, depending on the aryl ring substituents, exhibit solid-phase fluorescence from blue to red.
