مستخلص: A series of 6"-cyano-substituted spiro[indoline-2,3"-naphtho[2,1-b]oxazines] containing substituents with carbon chains of different lengths in the indoline fragment were synthesized. The structure of one of these spironaphthooxazines was established by X-ray diffraction analysis. The influence of substituents on the photochromic properties of the resulting compounds in solutions and polymeric films was studied. [ABSTRACT FROM AUTHOR]
