Synthesis and Properties of Bis-(phenylenedithio)-tetrathiafulvalene (BPhDT-TTF): a New ;r-Donor for Organic Metals

ثبت نشده
چکیده

The new 7r-donor bis-(phenylenedithio)-tetrathiafulvalene (5), synthesized via phosphite coupling o f 2-oxo-l,3-dithiolo-[4,5b][l,4]-benzodithiin (4), has been prepared in 5 steps start­ ing from 1,2-dimercaptobenzene and chloroacetyl chloride. Spectroscopic and electrochemical data point to a close similarity o f 5 and dibenzo-tetrathiafulvalene (DB-TTF). 5 forms a highly conducting radical-cation salt (crRT = 100 S/cm) with A sFfi" as counter ion.

Bis(vinylenedithio)tetrathiafulvalene analogues of BEDT-TTF

This review aims to give an overview of the current status of our research on the synthesis of π-electron donor bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF, ET) analogues prepared from 1,8-diketones via a ring forming reaction. The new synthesized π-electron donors have vinyl moieties producing extended π-electron delocalization over the substituent phenyl rings at the peripheries.

Modulation of the charge transfer and photophysical properties in non-fused tetrathiafulvalene-benzothiadiazole derivatives.

Bis(thiomethyl)- and bis(thiohexyl)-tetrathiafulvalene-bromo-benzothiadiazoles, containing electron donor tetrathiafulvalene (TTF) and electron acceptor benzothiadiazole (BTD) units, have been prepared by Stille coupling reactions between the TTF-SnMe3 precursors and BTD-Br2. In another series of experiments, TTF-acetylene-BTD compounds have been synthesized by Sonogashira coupling between eith...

Synthesis of bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF) derivatives functionalised with two, four or eight hydroxyl groups.

Short synthetic routes to a range of BEDT-TTF derivatives functionalised with two, four or eight hydroxyl groups are reported, of interest because of their potential for introducing hydrogen bonding between donor and anion into their radical cation salts. The cycloaddition of 1,3-dithiole-2,4,5-trithione with alkenes to construct 5,6-dihydro-1,3-dithiolo[4,5-b]1,4-dithiin-2-thiones is a key ste...

ORGANIC PHOTOCONDUCTOR TTF-TCNQ (TETRATHIAFULVALENETETRACYANOQUINODIMETHANE): A POTENTIAL ROOM TEMPERATURE INFRARED DETECTOR AT 10 ?m H. R. Mohajeri Moghaddam* and N. Peyghambarian

The absorption properties of charge transfer organic semiconductor TTF-TCNQ (tetrathiafulvalene-tetracyanoquhodimete ) filmsdeposited on KBr singlecrystal, quartz and glass substrates in far infrared have been investigated. An absorption edge at ?10 ??m was observed. Photoconductivity, photoconduction efficiency and gain and photocarrier's lifetime have been measured. The results show an el...

Acetylenic tetrathiafulvalene-dicyanovinyl donor-acceptor chromophores.

Compounds incorporating the tetrathiafulvalene (TTF) donor unit and one or two cyanoethynylethene (CEE) acceptor units were prepared by Knoevenagel condensations of highly unstable, TTF-linked propargylic aldehyde or ketone derivatives. The resulting TTF-CEEs are very strong chromophores with low-energy end-absorptions beyond 900 nm. The molecules experience reversible oxidations of the TTF uni...
