Abstract
We obtained β-diketone – 1-ferrocenylbutanedione-1,3 by Claisen condensation. Ligands - hydrazones of monocarboxylic acids 1-ferrocenylbutanedione-1,3 (H2L) were synthesized by the interaction of carboxylic acid hydrazides with ferrocenoylacetone. The optical properties of all compounds synthesized in the work have been studied; based on the absorption spectra data, the values of the optical band gap were determined; it was shown that all the synthesized compounds are d-π type chromophores and have a band gap of 1,39–2,26 eV, i.e. they belong to narrow-gap semiconductors.
