Although inorganic anion templates are highly appreciated in the synthesis of nanosized silver clusters,supramolecular clusters used as templates to mold silver nanoclusters remain as-yet-unknown due to their existence as volatile forms in ***,we report the synthesis of a novel silver-thiolate nanocluster(SD/Ag58a),comprising an outer tetrahedral cage of 58 silver atoms and a central supramolecular cluster[CH_(3)OH@(SO_(4))_(4)(H_(2)O)6]8−(hereafter abbreviated as CS_(4)H_(6)).Ternary CS_(4)H_(6) cluster was constructed from an(SO_(4))_(4) tetrahedron encaging one CH_(3)OH molecule inside and six water molecules sitting between paired SO_(4)^(2−)ions to form the[SO_(4)…H_(2)O…SO_(4)]hydrogen bonds(H-bonds).Also,the CS4H6 could coordinate to the inner wall of the Ag58 cage by forming Ag-O bonds,exerting templating effect on the formation of SD/***,SD/Ag58a showed a photocurrent response upon visible light irradiation and emitted luminescence in the near-infrared(NIR)region at a cryogenic *** work exemplifies the ternary supramolecule templating effect in the construction of silver nanocluster and facilitates understanding of the structure of complex solvated anion cluster in atomic precision.

用混酸处理多壁碳纳米管,利用侧壁生成的羧酸基团,在N,N-二环己基碳酰亚胺的作用下,使对氨基苯磺酸接枝到碳纳米管表面.以浓硫酸为磺化剂,室温下制备了磺化聚醚醚酮(SPEEK).然后采用溶液共混法制备了磺化聚醚醚酮/接枝多壁碳纳米管复合膜.采用傅立叶变换红外光谱(FT-IR)、热重分析(TGA)、透射电镜(TEM)、拉曼光谱(Raman)等技术对碳纳米管的结构和性能进行了表征.红外谱图表明对氨基苯磺酸上的氨基与碳纳米管表面的羧基发生了反应,生成酰胺基团.热重曲线表明碳管表面接枝的有机基团的比重达到40%.拉曼光谱显示处理前后碳管的ID/IG值变化不大,表明碳管的石墨结构的含量基本不变.复合膜的力学性能测试结果表明,对氨基苯磺酸接枝的碳管可以提高膜的拉伸强度.
