Abstract

The development of charge transfer materials accompanied by local excited state have been extensively studied in recent years owing to their potential applications in the field of photodetector, photocatalytic and solid-state lighting. Herein, the assembly of acridine (AD) organic cations and [ZnCl₄]^2- anions afforded one organic–inorganic hybrid complex [(AD)₂(ZnCl₄)] (1), which can be facilely synthesized in ethanol solution at room temperature for a few minutes. The alternately arranged AD cation π-conjugated system and [ZnCl₄]^2- inorganic anion tetrahedrons enable this hybrid complex with the mixture of local excited and charge transfer characteristic. It shows bright green light emission with long lifetime of 16.31 ns and quantum yield of 53 %. Theoretical calculations provided detailed energy level, band gap and charge distribution information of 1. Successful fabrication of green phosphor-converted light-emitting diode (LED) device making this hybrid complex perfect candidate for solid-state lighting material.

发光二极管用吖啶基杂化金属卤化物的电荷转移

伴随局部激发态的电荷转移材料由于在光电探测器、光催化和固态照明等领域具有潜在的应用前景，近年来得到了广泛的研究。本文通过吖啶（AD）有机阳离子与[ZnCl4]2-阴离子的组装，得到了一种有机-无机杂化配合物[(AD)2(ZnCl4)](1)，该配合物可以在乙醇溶液中室温合成几分钟。交替排列的AD阳离子π共轭体系和[ZnCl4]2-无机阴离子四面体使该杂化配合物具有局部激发和电荷转移的混合特性。它发出明亮的绿光，具有16.31 ns的长寿命和53%的量子产率。理论计算提供了1的详细能级、带隙和电荷分布信息。成功制造了绿磷转换发光二极管（LED）器件，使这种混合复合体成为固态照明材料的完美候选人。
