Photoisomerization of 1,3-bis(4-nitrophenyl)-1-butene was investigated.The quantum-yield value of photoisomerization depends on the nature of the solvent and on the wavelength of the excitation radiation.The photoisomerization velocity in alcohols is oxygen independent. 1,3-Bis(4-nitrophenyl)-1-butene reveals a phosphorescence spectrum with a triplet energy 19 600 cm-1 (234.42 kJ mol-1).The quantum yield of phosphorescence reaches values 10-3 up to 10-2.

Photolysis of 1,3-bis(4-nitrophenyl)-1-butene (I) in acetonitrile and 2-propanol by polychromatic radiation of a mercury lamp was studied.The photolysis kinetics was followed by UV spectra and the reaction products were analysed by IR and mass spectroscopy and by gas-liquid chromatography.The reaction mechanism is markedly affected by the presence of oxygen.Photolysis of I in acetonitrile gives mainly 4-nitrobenzaldehyde, n-heptane and toluene, in 2-propanol the principal products are stereoisomeric 1,3-diphenyl-1-butenes.

1,3-Bis(4-nitrophenyl)-1-butene was prepared by nitration of 1,3-diphenyl-1-butene (I) with fuming nitric acid in acetic acid.The double bond in I was protected by addition of bromine which was eliminated after the nitration.The UV, IR and 1H-NMR spectra
