We report a structure of ferrocene-pyrene conjugate (1) comprising electro and photo-active dual-signaling units. In particular, 1 upon interaction with Cu(II), displays selectively one-photon fluorescence quenching, but it shows two-photon absorption (TPA) cross-section 1230 GM (at 780 nm). Further, 1 displayed two irreversible oxidative waves at 0.39 V and 0.80 V (vs Ag/AgCl), in the electrochemical analysis which upon addition of Cu, led to the negative potential shift in both the oxidative waves to appear at 0.25 V and 0.68 V. The triple mode changes in presence of Cu(II) suggesting the possible application of 1 for the detection of Cu(II) in aqueous media. Graphical Abstract.
我们报道了一种包含电活性和光活性双信号单元的二茂铁-芘共轭物（1）的结构。特别地，1与Cu（II）相互作用时，选择性地显示单光子荧光猝灭，但它显示出双光子吸收（TPA）截面为1230 GM（在780 nm处）。此外，在电化学分析中，1在0.39 V和0.80 V（相对于Ag/AgCl）处显示出两个不可逆的氧化波，加入Cu后，两个氧化波的负电位均发生偏移，分别出现在0.25 V和0.68 V处。在Cu（II）存在下的三重模式变化表明1可能用于检测水性介质中的Cu（II）。图形摘要。
