dye 4-dimethylamino-1,8-naphthalimide was incorporated at the bay area of N,N'-bispyridyl perylene bisimide to afford a fourfold-functionalized perylene bisimide ligand. Through self-assembly directed by metal-ion coordination, a multichromophore supramolecular entity composed of sixteen dimethylaminonaphthalimide antennas and a perylene bisimide-walled square core was subsequently constructed from
将荧光染料4-二甲基氨基-1,8-萘二甲酰亚胺掺入N,N′-双吡啶基per双酰亚胺的湾区,得到四官能化的per双酰亚胺配体。通过金属离子配位的自组装,随后由该线性对位配体和90度金属角[Pd(dppp)](OTf)构成了一个多色团超分子实体,该实体由16个二甲基氨基萘酰亚胺天线和per双酰亚胺壁的方形核组成。 2(dppp = 1,3-双(二苯基膦基)丙烷; OTf =三氟甲磺酸盐),收率良好。通过元素分析和1H,13C和31P 1H} NMR和UV / Vis光谱对分离的金属超分子正方形进行表征。此外,通过1 H NMR扩散有序光谱法(DOSY),通过使用先前报道的bi双酰亚胺配体及其正方形组装体作为参考,评估该组装体的尺寸。获得的结果证实了当前程序集的方形框架。通过UV / Vis以及稳态和时间分辨荧光光谱研究了这种多发色团染料组件的光学性质。结果表明,通过二甲基氨基萘二甲酰亚胺天线
