Abstract
New photochromic 2,2-diphenyl-[2H]-chromenes 1–6 annellated with nitrogenated six-membered ring have been synthetized by optimized reaction of suitable metal phenolates and β-phenyl cinnamaldehyde. All compounds exhibit photochromic behavior at room temperature. Chemical yields and photochromic characteristics depend significantly on the relative position of annellation on the chromenic moiety.Keywords
