The aggregation-induced emission (AIE) properties of a systematic series of naphthalene diimides (NDIs) varying the length chain at the imide positions have been studied. A solvophobic collapse in water showed that NDIs with shorter chains favour the π-π stacking through H-aggregation producing a strong AIE effect. NDIs with longer chains lead to π-π stacking by J-aggregation unfavoring the AIE effect.

萘二酰亚胺的聚集诱导发射:链长对液相和固相发射性能的影响

研究了一系列不同酰亚胺位置链长度的系统萘二酰亚胺 (NDI) 的聚集诱导发射 (AIE) 特性。水中的疏溶剂塌陷表明,具有较短链的 NDI 有利于通过 H 聚集进行 π-π 堆积,产生强烈的 AIE 效应。具有较长链的 NDI 通过J聚集导致 π-π 堆积,不利于 AIE 效应。
