Structure and electronic properties of TTF bisannulated 24-crown-8 charge transfer complexes

Charge transfer (CT) complexes of tetrathiafulvalene bisannulated 24-crown-8 (1) with tetrafluoro (F 4)-, 2,5-dibromo (Br 2), 2,5-dichloro (Cl 2)-tetracyanoquinodimethane (TCNQ), and 2,3-dicyano-5,6-dichloro- p-benzoquinone (DDQ) were prepared. The electronic ground state of the acceptor varies from...

Description
Summary:	Charge transfer (CT) complexes of tetrathiafulvalene bisannulated 24-crown-8 (1) with tetrafluoro (F 4)-, 2,5-dibromo (Br 2), 2,5-dichloro (Cl 2)-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 1 2+. The molecular conformation of 1 2+ in Cl 2-TCNQ complex was an intra-dimer form folded over the flexible part of macrocyclic 24-crown-8.
