  Synthesis and Properties of 2,3,6,7-Tetrakis(alkoxymethyl)tetrathiafulvalenes

  摘要：

  A family of newly prepared tetrakis(alkoxymethyl)-substituted tetrathiafulvalene (TTF) derivatives 1 show melting point behavior typical for increasing length of their flexible alkyl chains and molecular weights. No evidence for the formation of a stable,liquid crystalline mesophase was found. The X-ray crystal structure of 1 (n = 7) shows it to have a flat central core. Its anodic reactivity is entirely parallel to that of tetrathiafulvalene itself. The dark conductivity of a thin film of 1 (n = 7) is sensitive to temperature, with dark conductivity being enhanced at higher temperatures by as much as 5 orders of magnitude from the level observed in previously studied TTFs. Short-circuit photocurrent is observed in a symmetrical ITO sandwich cell containing a thin layer of 1 (n = 7): in such a cell, charge can be separated under bias and maintained for at least 8 h.

  The cycloaddition of some alkynes with the tributylphosphine-carbondisulfide adduct provides the corresponding ylide, which in situ reacts with aldehydes by the Wittig reaction process to afford novel 2-arylidene or 2-alkylidene-1,3-dithioles in moderate yields.
