✦ Synopsis

Abstractz The multi-stage synthesis of new long-chain tetrathiafulvalene derivatives containing a diacetylene group at different distances from tetrathiivalene moiety -2-(tetracosa-9,ll_diynyle)-, 2-heptadeca-9, ll-diynyle)-and 2%(nonadeca-4,6-diynyle)-6,7-tetrathiafulvalene is described.

Recent developments in the field of creating conducting Langmuir-Blodgett films based on surface-active charge-transfer complexes and ion-radical salts of organic electrondonors and acceptors have stimulated interest in the synthesis of long-chain substituted derivatives of tetrathiafulvalene QTFJ '2. The complexes of e.g. heptadecyldimethyl TTF3 and hexadecyl BEDT TTF 4 have proved 5 to give relatively stable conducting LB films.

On the other hand, the diicetylenic compounds have attracted much attention due to their unique ability to form highly regular polymers upon irradiation which led us to the idea of combining the two types of compounds in the same molecule.
