Organic molecules such as tetrathiafulvalene (TTF) and its derivatives are important precursors in the design of new conducting, optical and magnetic materials. A new series of unsymmetrically tetrathiafulvalenes have been synthesised. The synthesis of p-acetoxyphenyl tetrathiafulvalenes 5a-d has been carried out by Wittig reaction and their deprotection leads to p-hydroxyphenyl tetrathiafulvalenes 6a-d. The structures have been assigned by 1H NMR spectroscopy and mass spectra. The reducing power of each new precursor has been determined by cyclic voltammetry. Charge transfer complexes of the donors with Tetracyanoquinodimethane (TCNQ) have been prepared and characterized. The electrical conductivity of these materials have been measured and discussed.
