Photochromic characteristics of spirocyclic organic and coordination compounds

Methods for the structural modification of photochromic spirocyclic systems (derivatives of spirobenzopyrans, spiro-1,3-oxazines, spiropyrimidines, and the bischelate complexes of nontransition metals), optimizing their spectral, kinetic, photochemical, and other characteristics in the direction required for their application as quick-acting chemical memory elements and in optical computers, are examined.Translated from Teoreticheskaya i Éksperimental'naya Khimiya, Vol. 31, No. 3, pp. 166–180, May–June, 1995.
