Photothermal perylene bisimide hydrogels [PDF]
Chemistry – A European Journal, 2023 Gels formed using a perylene bisimide (PBI) as a low molecular weight gelator can show the photothermal effect. Formation of the PBI radical anion results in new absorption bands forming, meaning that subsequent irradiation with a wavelength of light ...

Self-sorted Oligophenylvinylene and Perylene Bisimide Hydrogels [PDF]
Scientific Reports, 2017 We describe two component hydrogels with networks composed of self-sorted fibres. The component gelators are based on 1,4-distyrylbenzene (OPV3) and perylene bisimide (PBI) units.

Observation of Two-Exciton States in Perylene Bisimide Aggregates
EPJ Web of Conferences, 2013 The behavior of excitons on perylene bisimide aggregates is investigated at high excitation densities by femtosecond absorption spectroscopy. Indications for a significant population in the two-exciton manifold are found.

Switch of dimensionality of exciton diffusion in aggregates [PDF]
EPJ Web of Conferences, 2019 The ultrafast exciton dynamics in J-aggregates of a perylene bisimide dye is investigated for temperatures down to 77 K revealing at low temperatures a decrease of the exciton mobility and a change in the dimensionality.
