S2 emission from chemically modified BODIPYs

Abstract

Novel boron dipyrromethene (BODIPY) derivatives having significant absorption and emission in the longer wavelength region were synthesized. BODIPY showed anomalous S2 emission from the second excited (S2) state at shorter wavelength. The photodynamics of the S2 state was investigated by fluorescence up-conversion and transient absorption spectroscopic measurements. The decay time of the S2 emission was dependent on the internal conversion and the intersystem crossing process. The assignments of transitions were supported by a theoretical calculation based on the time-dependent density functional theory.
