Monomacrocycles of the two electron donors tetrathiafulvalene (TTF) and
1,5-dioxynaphthalene have been prepared, together with three symmetric
TTF-containing bismacrocycles, two of which have been prepared by a
two-step deprotection–cyclization approach. By utilizing the
donor–acceptor interactions of these donors with the dipyridinium
dication of 1,1′-[1,4-phenylenebis(methylene)]bis-4,4′-bipyri
dinium bis(hexafluorophosphate), [2]catenanes were synthesized. In the
case of one of the bismacrocycles it was possible to isolate a minor
amount of a bis[2]catenane. The catenanes were characterized
by
1
H NMR spectroscopy, electrospray mass spectroscopy (ESMS)
and their fragmentation in the gas phase was also analysed by collisional
activation (ESMS/MS).
Also, one tetramacrocyclic compound, the first TTF-based ribbon
compound, has been synthesized. This compound shows complex
electrochemical properties.
我们制备出了两种电子供体四硫代富戊二烯(TTF)和 1,5-二氧代萘的单双环化合物,以及三个对称的含 TTF 的双双环化合物,其中两个是通过两步脱保护-环化方法制备的。通过利用这些供体与 1,1′-[1,4-亚苯基双(亚甲基)]双-4,4′-联吡啶鎓双六氟磷酸盐的二吡啶鎓二ication 的供体-受体相互作用,合成了 [2] catenanes。在其中一个双环中,可以分离出少量的双[2]烯烷。通过 1 H NMR 光谱和电喷雾质谱(ESMS)对这些烯烷进行了表征,并通过碰撞活化(ESMS/MS)对其在气相中的碎片进行了分析。 此外,还合成了一种四环化合物,这是第一种基于 TTF 的带状化合物。该化合物显示出复杂的电化学特性。
