Triplet Generation in a Terrylene Bisimide Cyclophane by External Heavy Atom Effect of Encapsulated Brominated Pyrene Guest.
Generating triplet states in dye molecules that do not undergo conventional intersystem crossing is of interest for a variety of applications. In this work, the photophysical processes that occur in a terrylene bisimide (TBI) cyclophane and in its host-guest complex with 1,6-dibromopyrene (Ka = 1.5 × 104 M-1 in dichlor...
