Abstract
New nonsymmetric bis-spiropyran of the 2,3-dihydro-4-oxonaphtho[2,1-e][1,3]oxazine series was prepared. On the basis of the results of photochemical study and quantum-chemical calculations, it has been shown that both pyran cycles experience opening during irradiation of a bis-spiropyran solution with unfiltered light.
