SYNTHESIS AND OPTICAL PROPERTIES OF LEGENDS BASED ON FERROCENYLACETONE

##article.abstract##

We obtained fl-diketone-l-ferrocenylbutanedione - 1,3 by Claisen condensation.
Ligands-hydrazones o fmonocarboxylic acids l-ferrocenylbutanedione-1,3 (H2L) were syn-
thesized by the interaction O fcarboxylic acid hydrazides with ferrocenoylacetone. The optical
properties O fall compounds synthesized in the work have been studied; based on the absorp-
tion spectra data, the values o fthe optical hand gap were determined; it was Shawn that all the
synthesized compounds are d-N type chromophores and have a band gap o f 1,39- 2,26 house,
i.e. they belong to narrow-gap semiconductors.
