Highly transparent photochromic films with a tunable and fast solution-like response

The increasing interest towards photochromic films and their practical applications is driving researchers in the continuous design and synthesis of novel organic photochromic dyes with optimized performances in polymeric matrices. However, whereas their photochromic properties could be readily rati...
