Quantifying Triplet State Formation in Zinc Dipyrrin Complexes

, 2019
Photocatalysis is a promising method to harness solar energy and use it to form fuels and other high value chemicals, but most sensitizers used in photocatalytic reactions are complexes of rare and expensive metals such as ruthenium and iridium.

Direct Evidence of a Transition from Triplet Excitons to Hybrid Light-Matter States via Triplet-Triplet Annihilation

, 2020
In the enclosed manuscript, we embed a triplet-triplet annihilator inaccessible molecule inside an optical cavity. The system reaches the strong coupling regime, and the formed polariton has a reduced energy compared to the molecular singlet excited ...

Proton-Coupled Triplet-Triplet Energy Transfer: Carbon Monoxide Photorelease from Porphyrin-Flavonol Hybrids

, 2022
A new photochemical mechanism, termed proton-coupled energy transfer (PCEnT), was recently discovered in anthracene-phenol-pyridine triads (Pettersson Rimgard et al., Science 2022, 377, 742).

Calculation of pair and triplet correlation functions for a Lennard-Jones fluid at ρ*≤1.41 and T*≤25

AIP Advances, 2021
On the basis of Monte Carlo simulations, configurations and pair and triplet correlation functions for a Lennard-Jones fluid are reported over a large range of densities and temperatures (0.002 ≤ ρ* ≤ 1.41 and 0.45 ≤ T* ≤ 25, dimensionless).

Singlet/Triplet State Anti/Aromaticity of CyclopentadienylCation: Sensitivity to Substituent Effect

Chemistry, 2021
It is well known that singlet state aromaticity is quite insensitive to substituent effects, in the case of monosubstitution. In this work, we use density functional theory (DFT) calculations to examine the sensitivity of triplet state aromaticity to ...

Cool Carriers: Triplet Diffusion Dominates Upconversion Yield

, 2023
Perovskites have gained popularity both as the active material in photovoltaics and as bulk triplet sensitizers for solid-state triplet-triplet annihilation upconversion (TTA-UC).

Recombination dynamics in bacterial photosynthetic reaction centers [PDF]

, 1982
The time dependence of magnetic field effects on light absorption by triplet-state and radical ions in quinone-depleted reaction centers of Rhodopseudomonas sphaeroides strain R-26 has been investigated.

Singlet and Triplet Exciton Dynamics of Violanthrone

, 2021
The exciton dynamics of violanthrone-79 are investigated in solution and in the solidstate. In solution, the photo-prepared singlet is found to exhibit a strong ground-state bleachand stimulated emission feature, but when sensitized in its triplet state,

Triplet-State Photochemistry of Dissolved Organic Matter: Triplet-State Energy Distribution and Surface Electric Charge Conditions

, 2019
Excited triplet states of chromophoric dissolved organic matter (3CDOM*) are highly reactive species in sunlit surface waters and play a critical role in reactive oxygen species (ROS) formation and pollutant attenuation. In the present study, a series of
