Transient absorption of dyad 2 (Fig. 3A) and triad 1 (Fig. 3B) in benzonitrile upon femtosecond excitation at 740 nm presented in the form of EADS. (A) For dyad 2, global analysis yielded five components: 12 ps (black), 120 ps (red), 590 ps (green), 1.8 ns (blue), and nondecaying (turquoise). (B) For triad 1, global analysis afforded four components: 120 ps (red), 610 ps (green), 2.1 ns (blue), and nondecaying (turquoise). (A, Inset) Transient absorption kinetic traces in benzonitrile for dyad 2 at 650 nm (red) and 780 nm (pink) and for triad 1 at 780 nm (blue).
