一种用于金属离子和质子传感的不对称吡咯并吡咯二酮衍生物

An Asymmetric Diketopyrrolopyrrole Derivative for Metal Ion and Proton Sensing

吡咯并吡咯二酮(DPP)具有优秀的光学和电学特性,但其不对称衍生物的报道却很少。本文合成了一种含有乙烯基桥的不对称DPP衍生物TDB,并对其进行了表征。TDB在665nm处显示出了深红色至近红外(NIR)的荧光,对TDB的进一步研究表明,它对金属离子Ni^(2+)有良好的选择性,对H^(+)有较高的敏感性。

Diketopyrrolopyrrole(DPP) is well known of its optical and electrical properties, yet its asymmetric derivatives are less reported. In this work, an asymmetric DPP derivative TDB containing vinylene bridge is synthesized and characterized, exhibiting deep red to near-infrared( NIR) fluorescence over 665 nm. Further investigations of TDB show fine selectivity of Ni^(2+)and high sensitivity towards H^(+).
