| dc.description.abstractEn | Time-resolved transient absorption and gain spectra with subpicosecond laser excitation are reported for donor-donor and acceptor-donor stilbene-crowns (in each compound the electron donor group is the 15-aza-5-crown macrocycle, D<sub>1<sub/>). The effect of the calcium cation on the photoinduced intramolecular charge transfer (ICT) rate constants are measured. When the cation is on the donor side of the molecular system (class 1: D<sub>1<sub/>CS-Crown), the photoinduced ICT process is slowed down and goes through several intermediates characterized by a distancing of the cation, while a solvent molecule enters its coordination sphere. When the cation is on the acceptor side (class 2: D<sub>1<sub/>DS-Crown,D<sub>1<sub/>DB-Crown and D<sub>1<sub/>DCS-Crown), the photoinduced ICT process becomes too fast to be measured, even on the picosecond scale. | |
