Abstract The reaction between phenalenon derivatives containing hydroxy group in peri-position to carbonyl and propynol was studied. A new hybrid compound was synthesized, and its spectral-kinetic properties were measured. This compound has photochromic and fluorescent properties in one time.

New fluorescent switches with 2,3-diarylcyclopent-2-en-1-ones as the photochromic component and 6-ethoxy-3-methyl-1H-phenalen-1-one as the fluorophore have been prepared. Two approaches to develop the photoswitches have been applied. The first involves covalent binding of the fluorophore to photochromic diarylethene molecule by ether linkage. The second type of fluorescent switch was been prepared
