A Bodipy derivative with twisted pi-conjugation system is demonstrated that shows efficient intersystem crossing (ISC) (singlet oxygen quantum yield Phi(Delta) = 55%) and a long-lived triplet state (tau(T) = 197.5 mu s) with high energy (E-T1 = 1.44-1.53 eV). This is superior to the conventional heavy-atom-enhanced ISC in a reference Bodipy compound, which results in much shorter triplet state lifetime (3.3 mu s) and lower triplet-state energy (1.2 eV).
