A new tetranucleating macrocycle (H2L) comprised of 2,6-diformyl-4-methylphenol and 1,8-diamino-3,6-dimethyl-3,6-diazaoctane in the 2:2 ratio was obtained as a lead(II) complex of the formula Pb2(H2L)(dmf)4(ClO4)4, whose crystal structure was determined by X-ray method.

A series of thienylene-ethynylene-tetrathiafulvalene oligomers 1-6 have been synthesized by the Sonogashira reaction of iodo-tetrathiafulvalene derivatives with thienylethynes. The X-ray structure of 4,5-bis(2-thienylethynyl)tetrathiafulvalene (1b) revealed a planar structure of the molecule. The electronic spectra of neutral oligomers 1-6 suggest a partial intramolecular charge transfer between the TTF and thienylethyne units. The cyclic voltammetric measurements of 1-4 showed multi-redox processes.
