Synthesis and properties of 2,3,6,7-tetrakis(alkoxymethyl)tetrathiafulvalenes
- Univ. of Texas, Austin, TX (United States)
A family 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 temperature by as much as 5 orders of magnitude from the level observed in previously studied TTF`s. 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.
