Abstract :
Charge transfer (CT) complexes of tetrathiafulvalene bisannulated 24-crown-8 (1) with tetrafluoro (F4)-, 2,5-dibromo (Br2), 2,5-dichloro (Cl2)-tetracyanoquinodimethane (TCNQ), and 2,3-dicyano-5,6-dichloro-p-benzoquinone (DDQ) were prepared. The electronic ground state of the acceptor varies from the completely ionic to partial charge transfer state. Within the CT complexes the donor 1 was completely oxidized to the divalent cationic state 12+. The molecular conformation of 12+ in Cl2-TCNQ complex was an intra-dimer form folded over the flexible part of macrocyclic 24-crown-8.
