Аннотация:
Complexation with strong competitors (i.e., Ba2+, Ca2+, and K+) shortens the length of the chromophore in bis-aza-18-crown-6-containing dienones of 2,4-dibenzylenecyclobutanone series due to the weakening of π–LP conjugation as
well as disruption of the quinonoid structure in the ground state of the dye (LP is the lone electron pair of the crown nitrogen atom). In the excited state, recoordination of metal cations in the crown cavity takes place. The complexation as well as the newly discovered photorecoordination in these
metal complexes may be used to control the chromophore properties of the samples.
Ключевые слова:
