Abstract

Chiral oligopeptide-naphthalene/Eu(iii) hybridized luminophores emit strong circularly polarised solution-state luminescence (CPL) from Eu(iii) at 592 and 614 nm (| | ≤ 2.1 × 10). Although the peptide ligands have matching absolute configurations, the CPL sign is controllable by varying the number of naphthalene units and peptide/Eu(iii) coordination ratio.

摘要

手性寡肽-萘/Eu(III)杂化发光体在592和614纳米处从Eu(III)发出强烈的圆偏振溶液态发光(CPL)(| |≤2.1×10)。尽管肽配体具有匹配的绝对构型，但通过改变萘单元的数量和肽/Eu(III)配位比，CPL信号是可控的。
