[14p-1E-14] Preparation of Molecular Assembly Composed of Organic Conducting Derivatives Having Ether Groups in Side Chains
Keywords:Charge-Transfer Complex,Self Assembly
Molecular self-assembling processes can show special physical properties of conducting and magnetic properties and many nano devices composed of the functional small molecules have been reported. The p-conjugated molecules have the interest physical properties because of their great potential for the directional transportation of electrons. Donor molecules such as Tetrathiafulvalenes (TTF) show the high conductivities at room temperature in crystalline states.
In this presentation, we report the synthesis and physical properties of new TTF derivatives and TCNQs. At first, we synthesized TTF derivatives having ether alkyl chains (TTF-1IO, TTF-2IO). After mixing these TTF derivatives and TCNQs in chloroform solution we could get the charge transfer complexes. By applying various deposition techniques for new derivatives and acceptors, the synthesized molecules could be organized in nano structures due to the intermolecular interactions on the solid substrates. The UV-vis spectra show the absorption of cation radical of TTF and anion radical of TCNQ around 450 and 800 nm, and IR spectra have broad absorption of CT composed of complexes at 2500 - 4000 cm. These result investigated that these CT complexes formed the partially CT state. We measured the conductivities, SQUID and ESR, these physical properties of CT complexes will be discussed.
