Study on photochromic behaviour of organic dyes in solution form using multilevel factorial design

Photochromic compounds, namely spiropyran, spirooxazine, and naphthopyran, have received much attention, be-cause of their high potential applications in various industrial fields. The aim of this study is to understand the be-havior of three photochromic dyes in solution form via statistic...
