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 λmax of the visible spectra of t...
