Photochromic properties of six 5-O-n-alkyl, 6-CN substituted spironaphthoxazines

The photochromic properties of a series of six 5-O-n-alkyl, 6 -CN substituted spironaphthoxazines has been investigated in toluene and methanol solution. The 6 -CN and 5-O-n-alkyl substitutions lead to a bathochromic shift of the UV spectra of the closed forms. The max of the visible spectra of the...
