Synthesis and spectral-luminescence properties of 4,4′-di(2-oxazolyl)-stilbenes and 4,4′-di(2-oxazolyl)tolans

Article abstract of DOI:10.1007/BF00503327

A new method is proposed for the synthesis of 4,4′-di(2-oxazolyl)stilbenes and 4,4′-di(2-oxazolyl) tolans by condensation of oxazolyl-substituted benzyl bromides or benzal dibromides under the influence of strong bases (KOH, potassium tertbutoxide) in dipolar aprotic solvents [dimethylformamide (DMF) and dimethyl sulfoxide (DMSO)]. The synthesized compounds luminesce intensely over the spectral range 386-492 nm.
