A pyrene-armed hexahomotrioxacalix[3]arene as a multi-sensor via synergistic and demetallation effects

[摘要] A new pyrene-armed hexahomotrioxacalix[3]arene L has been synthesized, which exhibits a pronounced fluorescence enhancement response toward Cu2+ ions via a Zn2+ or Cd2+ triggered synergistic effect. Additionally, the L.Cu2+ complex can subsequently serve as a sensor for F- via anion-induced demetallation. The fluorescence responses by the input of Cu2+, Zn2+/Cd2+ and F- can be constructed as a combinational logic gate which mimics a set of molecular traffic signals. (C) 2015 Elsevier Ltd.
