Abstract

The photochromic behavior of a spiroperimidine compound, 2, 3-dihydro-2-spiro-7′-(8′- imino-7′, 8′-dihydronaphthalen-1′-amine) perimidine (PNI), doped in various polymers has been studied. Upon irradiation with 405 nm light, PNI exhibits photochromism, and a color change (light yellow to brown) is observed. The initial (closed) and colored (open) forms exhibit absorption maxima (λmax) around 400 and 500 nm, respectively. The open ...
