Witryna8 sie 2002 · Thin films of pyrene in polystyrene matrix have been prepared by spin coating technique. The concentration of polystyrene is kept constant to 1 wt.% while that of pyrene dopant varied in the range 2.30×10 −4 –2.30×10 −1 wt.%. Thickness of the films was found to depend upon concentration of pyrene and varies from 90 to 782 … Witryna13 maj 2024 · Recent efforts in designing new 3H-naphthopyran derivatives have been focused on efficient coloration process with a short fading time of the colored transoid-cis TC isomer. It is desirable to avoid photoisomerization of TC leading to transoid-trans TT isomers in the photoreaction. Long lifetime of TT can hamper fast applications such …
