  Geometrically Constrained Tetrathiafulvalenophanes:  Synthesis and Characterization

  摘要：

  The synthesis of tetrathiafulvalenophanes 4b, 4c, 5, 9, and 10 employing two fundamentally different strategies is reported. Macrocycle 9 was obtained as a mixture of cis and trans isomers and was crystallized to afford two distinct crystals types: a red type consisting of the cis isomer and a yellow type consisting of the trans isomer. The crystal structures of cis-9 and trans-9, determined by X-ray diffraction, revealed that the cis-form possesses a planar TTF moiety while the trans-form has a distorted TTF unit. The electrochemical properties of the new tetrathiafulvalenophanes are reported.

  Two linear oligo-TTFs were synthesised employing a stepwise strategy involving two different thiolate protecting groups. These linear TTFs were incorporated into donor–acceptor rotaxanes with the cyclic acceptor, cyclobis(paraquat-p-phenylene). Moreover, a prototype rotaxane based on a bis(pyrrolo)-TTF was prepared and studied.

  采用涉及两种不同硫醇酯保护基团的分步策略，合成了两种线性寡 TTF。这些线性 TTF 与环状受体环双（百草枯对苯二甲酸酯）结合成了供体-受体轮烷。此外，还制备并研究了一种基于双（吡咯）-TTF 的轮烷原型。
