Preparation and optical limiting properties of a novel POSS-based organic-inorganic hybrid nanocomposite

以二苯乙烯衍生物4-乙炔基-4′-硝基二苯乙烯(ENS)和POSS(T8H)为原料,通过钯催化硅氢化反应制备了POSS基有机/无机纳米杂化复合材料(POSS-ENS),并用IR、1H NMR、29Si NMR、UV-vis对其结构进行了表征.同时,对材料的光限幅性能和热性能进行了测试,结果表明,纳米杂化复合材料不仅对532nm、4ns脉宽的激光具有良好的光限幅效应,而且具有很好的光学稳定性和热稳定性能.
