A study has been made of the spectral and photochemical properties of a series of heterocyclic analogs of 4-azidochalcone, specifically the pyridine, quinoline, isoquinoline, and quinoxaline derivatives.It has been shown that the absorption spectra of most of the 4-azidocinnamoylarenes are shifted bathochromically in comparison with 4-azidochalcone.The quantum yields of photodissociation of the compounds that were investigated were found to vary within the limits 0.70 +/- 0.15.With steric hindrance for the planar conformation of the molecule, a hypsochromic shift ofthe absorption spectra is observed, along with a slight decrease of the quantum yield.
