中文摘要：

有机发光材料在电致发光与显示器件领域有着非常广泛的应用。以具有高荧光量子产率的长共轭芴类衍生物2-乙炔基-7-（4-（4-甲氧基苯乙烯基）苯乙烯基）-9,9-二辛基芴（EMOF）和POSS（T8H8）为原料,通过硅氢化反应制备了POSS基有机/无机杂化分子发光材料（EMOF-POSS）,并用FT-IR、1H-NMR和13C-NMR对其结构进行了表征。通过紫外-可见和荧光光谱研究了EMOF和EMOF-POSS在不同比例的THF/H2O混合溶剂中的聚集效应,并对两者的热性能进行了测试。结果表明,EMOF-POSS不仅具有较好的热稳定性,而且有效地降低了荧光生色团的聚集,从而提高了材料的荧光量子产率（ΦFL）和发光性能。

英文摘要：

A kind of luminescent POSS-based organic/inorganic hybrid nanocomposite（EMOF-POSS） was prepared by the Pt-catalyzed hydrosilylation reaction of POSS（T8H8） and 2-ethynyl-7-（4-（4-methoxystyryl）styryl）-9,9-dioctyl-9H-fluorene（EMOF） with the high photoluminescence quantum efficiency（ΦFL）,and its structure and property were characterized by FT-IR,1H NMR,13C NMR,TGA,DSC,UV and PL,respectively. The influence of aggregation effects of EMOF and EMOF-POSS on their electronic absorption and luminescent properties were investigated in detail. The results show that the incorporation of POSS effectively restrains the aggregation effect of organic luminescent chromophores and enhances the photoluminescence quantum efficiency of hybrid. Simultaneously,the resultant hybrid shows significantly improved thermal stability.
