文摘

Four BODIPY dyes with π-extended substituents in 8-position were investigated in solvents and polymers. Substituent influence on photophysical properties and photostability of the compounds are discussed. Aggregation induced spectral changes were observed. Displacement of monomer-aggregate equilibrium was exploited for tuning electroluminescent characteristics of OLED devices.
