摘　　要：根据四硫富瓦烯独特的电化学性质和杯芳烃的分子平台特性,设计合成了两种新型的醚键连接的四硫富瓦烯-杯芳烃衍生物4a和4b,并通过核磁共振谱、红外光谱、质谱和元素分析等手段对其进行了表征.循环伏安法研究结果表明,化合物4a和4b均呈准可逆氧化还原行为.同时,利用紫外-可见光谱法研究了金属离子(Na+,K+和Ba2+)对化合物4a和4b作为电子供体分别与电子受体四氯苯醌分子间电子转移的影响,结果表明,K+能够有效地促进化合物4b与四氯苯醌的分子间电子转移.上述研究结果对于开发基于四硫富瓦烯的分子间电子转移的超分子体系具有重要意义.Based on the redox behavior of tetrathiafulvalene and unique platform of calixarene,two ether-linked tetrathiafulvalene-calixarene derivatives（4a and 4b） were designed and synthesized,which were characterized by 1H NMR,13C NMR,FAB-MS,IR and elemental analysis.Their electrochemical properties were investigated by cyclic voltammetry method and two quasi-reversible waves with redox potentials were observed.Meanwhile,the UV-Vis spectra was used to exploit the intermolecular electron transfer between the target compound（4a and 4b） and tetrachloro-1,4-benzoquinone（Q） regulated by metal ions（Na＋,K＋ and Ba2＋）.The results show that the K＋ may effectively promote the electron transfer between 4b and Q system,which will be helpful to develop TTF-based supramolecular systems for intermolecular electron transfer.
