Abstract:
Synthesis of BEDT-TTF donors with three-fold symmetry The BEDT-TTF derivatives have been a major focus for research in the preparation of molecular conducting systems and radical cation salts. Special attention is given in this work, to the preparation of compounds with more than one unit of BEDT-TTF units with the aim to prepare new materials with different crystal packing arrangements and thus new possible physical properties. The preparation of a BEDT-TTF or ET derivatives with a hydroxymethyl group (HMET) was carried out successfully and HMET ester of isonicotinic acid was prepared. Only metal complexes with copper ions were prepared and none of them presents more than one ET unit. Two approaches were proposed for the synthesis of the HMET triester of trimesic acid considering the two key reactions for the preparation of BEDT-TTF derivatives: the coupling reactions and the esterification. The experimentation carried out shows better results when the HMET donor is prepared first and then attached to the central core.
