以1，3，5-苯为核，分别被三个相同的基团取代，即-CH=H（TTF）（8）（TTF=四硫富瓦烯），-CH 2S（（TTF）Me 3）（9），1，4-二硫富烯-6-基（10 a，B）和6-甲基-1，4-二硫富烯-6-基（11 a，B）.循环伏安实验表明，10 a，B的氧化引起的电活性聚合物在电极上的沉淀，而9可以可逆地氧化为9 3+和9 6+。在TBA 2（Mo 6Cl 14）存在下9的电结晶得到（92+）·Mo 6Cl 142-晶体，用EPR研究了其磁性
Novel π-donor molecules with 3-fold symmetry are built on the 1,3,5-benzene core, substituted with three identical moieties, i.e. -CH=H(TTF) (8) (TTF=tetrathiafulvalene), -CH 2 S((TTF)Me 3 ) (9), 1,4-dithiafulven-6-yl (10a,b), and 6-methyl-1,4-dithiafulven-6-yl (11a,b). Cyclic voltammetry experiments demonstrate that oxidation of 10a,b gives rise to the precipitation of an electroactive polymer on the electrode, while 9 can be reversibly oxidized to 9 3+ and 9 6+ . Electrocrystallization of 9 in the presence of TBA 2 (Mo 6 Cl 14 ) affords crystals of (9 2+ ).Mo 6 Cl 14 2- , whose magnetic properties are investigated by EPR
