Abstract
In this paper the synthesis and spectral properties of three new dimeric bis(BODIPY)s with two indacene domains connected by a methylene (-CH2-) spacer at 2,2-, 2,3- or 3,3- positions were reported. It was found bis(BODIPY)s exhibit a high sensitivity of fluorescence to the medium properties. To interpret solvatochromic effects of bis(BODIPY)s, a multilinear correlation analysis of bis(BODIPY)s fluorescence quantum yields with respect to solvent different parameters was carried out. To understand the features of the spectral properties of bis(BODIPY)s, we carried out a thorough quantum-chemical analysis of the structural, conformational, and spectral characteristics of bis(BODIPY)s. The obtained bis(BODIPY)s have a high potential for application as sensors of medium polarity.
