Abstract

The synthesis of 3H-naphtho[2,1-b]pyrans 9-21 linked to a thiophene moiety is described. Two different synthetic approaches were applied to prepare these novel functionalized compounds, and their spectrokinetic properties in solution are reported. ... Introduction. - In the last decade, research in the area of photochromic coinpounds has increased significantly, due to their promising applications in optical technology as well as in the design of ...
