Multitarget synthetic strategies to access novel photochromic 3H-naphtho2,1-bpyrans decorated with pyridyl units are described. The new pyridyl-substituted 3H-naphtho2,1-bpyrans 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.
