A new chalcone-based probe for the chromofluorogenic sensing of trivalent (Al , Fe , Cr , Ga , In and As ) over mono- and divalent cations and anions is reported. In the presence of trivalent metal cations, the probe was able to display a remarkable color change from yellow to colorless that was clearly visible to the naked eye. Also, the initial strong yellow emission was gradually quenched and substituted by a weakly shifted band.
报道了一种基于查尔酮的新型探针,用于对三价阳离子(铝、铁、铬、镓、铟和砷)相对于一价和二价阳离子及阴离子进行发色荧光传感。在三价金属阳离子存在下,该探针能够呈现出从黄色到无色的显著颜色变化,肉眼清晰可见。此外,最初强烈的黄色发射逐渐猝灭,并被一个微弱位移的谱带所取代。
