| 中文摘要: |
| 以亚磷酸三乙酯为耦合剂，我们通过偶联反应得到苯甲酸(酯)修饰的四硫富瓦烯衍生物，电子给体TTF-ph-COOCH3 (ph = 苯基), 7，电子给体7水解得到含苯甲酸的电子给体TTF-ph-COOH (ph = 苯基), 8。利用1H NMR，MS等对化合物7和8进行了表征。化合物7和8的电化学性质表现出TTF体系特有的两对氧化可逆的单电子峰；同时，化合物7和8在UV-vis光谱上都有D-A的ICT的吸收峰，从ICT吸收的强度比较，化合物8中存在更强的D-A的相互作用，这和相对电子给体7，电子给体8具有更高的氧化电位相吻合。同时，我们得到了制备化合物1和2的关键中间体化合物5的单晶，并对其单晶结构进行了解析。 |
| 英文摘要: |
| Two tetrathiafulvalenes substituted with a phenyl (Ph) group (TTF-A) [A = Ph-COOCH3 1 and A = ph-COOH 2] have been synthesized to clear the nature of the donor–acceptor interaction between the TTF unit and the acceptor group, and characterized by 1H NMR, mass spectra etc.The two compounds display two reversible redox peaks corresponding to the TTF/TTF ? and TTF ?/TTF2 and show the similar redox potentials comparable to other ph-substituted TTF derivatives. And the results indicate that compound 1 and 2 are good donor molecules. And we also got crystal of the key compound 3 for compound 1 and 2. The compound 3 belongs to monoclinic space group Pc with cell parameters a = 0.3890 (1) nm, b = 1.065 (1) nm, c = 1.318 (1) nm, Z = 2, V = 534.5 (2) nm3, Dc = 1.542 g.cm–3, F(000) = 260, R = 0.0467, wR = 0.0739 (I > 2σ (I)). |
