Ultrafast exciton dynamics in a branched molecule investigated by time-resolved fluorescence, transient absorption, and three-pulse photon echo peak shift measurements

Article Abstract:

The excited-state dynamics of a branched octupolar molecule (tris-4, 4E, 4"-(4-nitrophenilethynyl) triphenylamine (T-NPTPA) with charge transfer character is investigated by complementary measurements of time-resolved fluorescence, transient absorption, and three-pulse photon echo peak shift. The data are compared with those obtained for the linear molecule dimethylnitroaminotolane (DMNAT) representing a linear building block of the octupolar system.
