Excited-state dynamics of astaxanthin aggregates
Original language description
Astaxanthin forms three types of aggregates in hydrated dimethyl sulfoxide (DMSO). In DMSO/water ratio of 1:1, a red-shifted J-aggregate with maximum at 570 nm is generated, while a ratio of 1:9 produces blue-shifted H-aggregates with peaks at 386 nm (H1) and 460 nm (H2). Monomeric astaxanthin in DMSO has an S-1 lifetime of 5.3 ps, but a long-lived (33 ps) S* signal was also identified. Aggregation changes the S-1 lifetimes to 17 Ps (H1), 30 Ps (H2), and 14 ps (J). Triplet state of astaxanthin, most likely generated via singlet homofission, was observed in H1 and H2 aggregates.
