Phenol substituted 1,8-naphthalimide derivatives acting as a donor and an iridium(III) complex which emits orange light acting as an acceptor were synthesized to fabricate a novel white-light-emitting two-component gel. The intermolecular energy transfer between the two components plays a crucial role in providing the tuneable emission in the mixed gels. The emission of white light can be obtained by carefully tuning the ratio of the two components. These gels are ideal constituents for the design of supramolecular light-harvesting materials, which afford a novel approach to displaying information in soft materials with tuneable optical properties. Furthermore, the two-component gel can respond to cysteine with an obvious change in luminescence that is visible to the naked eye.
通过合成作为供体的苯酚取代 1,8-萘二甲酰亚胺衍生物和作为受体的可发出橙色光的铱(III)复合物,制造出了一种新型白光发光双组分凝胶。这两种成分之间的分子间能量转移在混合凝胶的可调发射中起着至关重要的作用。通过仔细调节两种成分的比例,可以获得白光发射。这些凝胶是设计超分子光收集材料的理想成分,为在具有可调光学特性的软材料中显示信息提供了一种新方法。此外,这种双组分凝胶还能对半胱氨酸做出反应,产生肉眼可见的明显发光变化。
