报道了氢化锂-聚乙炔复合材料（LiH-PA）的储/放氢现象。LiH-PA可逆释放2.7 wt %的氢。同位素实验和拉曼光谱分析表明，氢的释放/储存反应是通过H -和聚乙炔之间的电子转移进行的。这是利用电子转移在共轭大分子中储氢的首次报道。
The hydrogen storage/release phenomena on a lithium hydride-polyacetylene composite (LiH-PA) are reported. LiH-PA reversibly releases 2.7 wt % hydrogen. Isotopic experiment and Raman spectroscopy reveal that hydrogen release/storage reaction proceeds via electron transfer between H– and polyacetylene. This is the first report that employs electron transfer in conjugated macromolecules for hydrogen storage.
