Authors

We obtained β-diketone, 1-ferrocenylbutanedione-1,3, by Claisen condensation. Ligands - hydrazones of monocarboxylic acids
1-ferrocenylbutanedione-1,3 (H 2 L) 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.
