摘要: A sensitive and selective “turn-on” fluorescent probe (compound 1O) was prepared by combining a photochromic diarylethene with rhodamine unit. This compound displays favorable photochromism on alternating irradiation UV/Vis light. Upon addition of Al(III) or Cr(III) to the probe, its color changes from colorless pink, fluorescence is markedly enhanced. The excellent sensitivity selectivity for these ions. Another 1C) also found undergo change pea green pink after binding 30(III). Sensitivities were studied, competition experiments various other metal ion revealed that 1C possesses good response Cr(III).
