Several boron-dipyrrin (BODIPY) based fluorophores with two and three dipyrrin cores were synthesized and investigated in solvents under the concentration variation. Comparative analysis of spectral and photophysical changes under increasing the number of the cores in the dye molecule was made. Mutual influence of dipyrrin cores was detected leading to the increasing of the compounds rigidity and, thus, the absence of fluorescent molecular rotor effects under the viscosity variation. Aggregation induced quenching, which was observed for many mono-domain BODIPY dyes is reduced in case of investigated poly-domain compounds.
合成了几种具有两个和三个二吡咯核心的基于硼二吡咯（BODIPY）的荧光团，并在不同浓度的溶剂中进行了研究。对染料分子中核心数量增加时的光谱和光物理变化进行了比较分析。检测到二吡咯核心之间的相互影响，导致化合物刚性增加，因此在粘度变化时不存在荧光分子转子效应。许多单域BODIPY染料中观察到的聚集诱导猝灭在研究的多域化合物中有所减少。
