【摘要】 以二(碘乙基)醚和2,3-二氰乙硫基四硫富瓦烯衍生物作为起始原料,采用腈乙基保护与脱保护技术,通过多步反应以较好的收率合成了两个纳米结构的大环四硫富瓦烯冠醚5a～5b.通过循环伏安法(CV)研究了化合物4b和5b的电化学性质,并用HNMR谱研究了5b与[60]富勒烯之间的相互作用.结果表明:5b存在环结构效应,与[60]富勒烯有一1定程度的电荷转移相互作用.更多还原

【Abstract】 Two nanoscale crown ether annulated tetrathiafulvalene (TTF) tetramers 5a～5b were synthe- sized via several steps using bis(2-iodoethyl)ether and 2,3-biscyanoethyl TTF derivatives as starting materi- als by cyanoethyl protection/deprotection method. The electrochemical properties and charge-transfer (CT) interaction with [60]fullerene of open chain TTF tetramer 4b and the above mentioned macrocyclic com- pound 5b were studied by means of cyclic voltammetry (CV) and H NMR spectroscopy, and 5b showed 1 macrocyclic effect and the considerable charge-transfer interaction with [60]fullerene.更多还原
