Organic luminescent materials with strong solid-state emission have gained great interest for their important use in the applied fields of electroluminescence devices.1The aggregation caused by the strong intermolecular p–pinteraction in the solid state generally debases or quenches the emission.2 Aggregation quenching is considered as an intractable problem in the devel-opment of devices because organic materials are normally used as thin solid films, and that aggregation inherently accompanies film formation. Thus, it is highly desirable to develop lumines-cent materials that emit intense light in the solid state and can overcome the aggregation-quenching problem. Recently, an unusual phenomenon, where some luminescent molecules have enhanced emission in the solid state, referred to as aggregation-induced emission (AIE)3 or aggregation-induced emission enhancement (AIEE),4 has been observed. This phenomenon offers a new path in solving problems on aggregation-caused quenching |

具有较强固态发光的有机发光材料已在电发光器件的应用领域因其重要用途而获得了巨大的利益【1】。 在固体状态下,强烈的分子间π-π相互作用所致的聚合通常削弱或猝灭发光【2】。聚合猝灭在器件的开发中被认为是一个棘手的问题,因为有机材料通常用作薄固体膜,在膜的形成中总是伴随聚合。因此,非常需要开发出在固体状态下发出强烈的光线,并可以克服聚合猝灭问题的发光材料。最近有一个不寻常的现象,已经观察到一些发光分子具有增强的固态发光,称为聚合诱导发光(AIE)【3】或聚合诱导发光增强(AIEE)【4】。这种现象为解决聚合引起的猝灭问题提供新的途经。 |
