| Abstract: | Two novel photochromic dithienylethenes compounds, 1,2-bisperfluorocyclopentene (1a) and 1,2-bisperfluorocyclopentene (2a) were synthesized, and their UV-Vis absorption spectra, fluorescent properties and photochromic dynamics character were studied in different solvents and concentrations. The results indicate that they have not only shown good photochromic behavior and strong fluorescent properties, but also their cyclization reactions are zeroth order reaction and cycloreversion reactions are first order reaction. |
| Keywords: | diarylethene photochromism fluorescence UV-Vis spectra |
