Beschreibungen/Notizen

• Multitarget synthetic strategies to access novel photochromic 3H-naphtho­[2,1-b]­pyrans decorated with pyridyl units are described. The new pyridyl-substituted 3H-naphtho­[2,1-b]­pyrans display good photochromic properties with reversible generation of photomerocyanines, which exhibit mainly orange/red hues. Photochromic parameters including photocolorability and persistence of color vary tremendously on structural modification of the naphthopyran core.
