中文摘要：
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。
英文摘要：
A kind of POSS-based organic-inorganic hybrid nanocomposite （POSS-ENS） was prepared by the Ptcatalyzed hydrosilylation reaction of POSS （T8H） with 4-ethynyl-4′-nitrostilbene （ENS）, and its structure and properties were characterized and evaluated by FT-IR, ^1H NMR, 29 Si NMR, UV-vis and optical limiting analyses, respectively. The results show that the organic-inorganic hybrid nanocomposite not only exhibits good optical limiting effects to 532nm, 4ns pulses width laser, but also possesses well photostability and high thermal stability.
