Dip-dyed: New boron-dipyrromethene (BODIPY) dyes linked to viologen are prepared, and their photophysical and electrochemical properties are investigated. They exhibit well-defined redox behavior, highlighting the presence of BODIPY and viologen subunits. Transient absorption techniques demonstrate that photoinduced electron transfer is promoted, and the lifetime of the charge separated state depends on the substitution position.
