A new donor for charge-transfer systems: synthesis and properties of 2,4,7,9-tetramethyl-1,6-dithiapyrene (TMDTP) and structure of (TMDTP)3(PF6)2·2THF and TMDTP-TCNQ.
Ontology highlight
ABSTRACT: The heterocyclic donor molecule 2,4,7,9-tetramethyl-1,6-dithiapyrene (TMDTP) has been synthesized in five steps. Oxidation of TMDTP is facile (E 1 1/2 = 0.27 V and E 2 1/2 = 0.79 V vs. SCE). The charge-transfer complex, TMDTP-TCNQ, has been prepared and the salt, (TMDTP)3(PF6)2·2THF, obtained by electrocrystallization. The structure of TMDTP, TMDTP-TCNQ and (TMDTP)3(PF6)2·2THF has been characterized by X-ray crystallography and computationally.
