| 제목 | Acid(g)/base(g)-controlled reversible Δν1/2 of absorption spectrum of a squarylium dye |
| 초록 | In this presentation, we introduce reversible modulation of absorption band width of squarylium dye (SQ1) using SQ1’s reversible reactivity with acid and base gases. SQ1 showed reversible gasochromic behavior by changing its color between purple and sky blue in response to ethylamine and hydrochloric acid gases. From the characterization of 1H NMR, UV-Vis absorption spectra and surface morphology, we revealed the mechanism of reversible absorption band width changes of SQ1 |
