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.

摘要:

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.

Synthesis of stable caesium salts of tetrathiafulvalene- and 1,3-dithiole-2-thionethiolates and their reaction with tetrakis(iodoalkylthio)tetrathiafulvalene to produce pentakis(tetrathiafulvalenes) is presented. X-ray structure of the caesium salt of 1,3-dithiole-2-thione-5-methoxycarbonyl-4-thiolate reveals a highly conjugated system.
