倍半硅氧烷基电致发光材料的研究进展

有机电致发光器件(OLED)作为一种新型显示器件,其结构简单、易于制造、成本更低、性能更好,未来在各领域将有很大的应用潜力。其中电致发光材料是OLED的核心材料,是OLED能否工业化生产的关键因素,但目前发光材料仍存在一些不足。多面体倍半硅氧烷(POSS)作为一种笼状无机材料,由于具有良好的耐热性、力学强度、稀释效应,经常与咔唑、芴等有机物杂化,从而有效地改善光电和物理性能,被用作OLED电致发光材料,已得到当前电致发光研发领域的极大关注。本文主要介绍了倍半硅氧烷基电致发光材料的研究进展。

Advances in POSS-substituted Lighting Emitting Materials

Organic lighting emitting diode(OLED) as a novel display device,which has the characteristics of simple structure,easy for manufacturing,low cost and better stability,is expected to have great potential for future application in various fields.Luminescent materials is a critical factor to the mass industrialization of OLED,but there are some drawbacks with it.In current light-emitting fields,as a sort of light-emitting materials in OLED,considerable attention has been focused on polyhedral oligomeric silsequioxane(POSS),which has good thermal stability,mechanical strength,effective dilution effect when hybrided with organic monomers,such as fluorene and carbazole.The recent development in POSS-substituted luminescence materials of cagelike and side-chain-tethered structure were summarized.
