Triplet-state phosphoryl biradicals

Synthetic Metals, 1995
The first example of triplet-state phosphoryl diradicals is reported. Photoinduced dissociative electron capture of two diastereoisomeric m-phenylenebis(ph0sphinic ch1oride)is in a glassy toluene matrix at 130 K using an electron-rich olefin affords the corresponding hosphoryl monoradicals and triplet-state diradicals in a 5:2 ratio.

Using Genetic Algorithms to Discover Novel Ground- State Triplet Conjugated Polymers [PDF]

, 2022
Stable ground-state triplet π-conjugated copolymers have many interesting electronic and optoelectronic properties. However, the large number of potential monomer combinations makes it impractical to synthesize or even just use density functional theory (

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).

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.

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

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 ...

N,N′-Diaryldihydrophenazines as a Sustainable and Cost-Effective Alternative to Precious Metal Complexes in the Photoredox-Catalyzed Alkylation of Aryl Alkyl Ketones

Molecules, 2022
An inexpensive and highly efficient metal-free alternative to commonly used Ru- and Ir-based catalysts was proposed. It was shown that the new 2,7-di-tert-butyl-5,10-bis(4-trifluoromethylphenyl)-5,10-dihydrophenazine outcompeted the iridium phenylpyridyl

Study on the Development of Neutrosophic Triplet Ring and Neutrosophic Triplet Field [PDF]

, 2018
Rings and fields are significant algebraic structures in algebra and both of them are based on the group structure. In this paper, we attempt to extend the notion of a neutrosophic triplet group to a neutrosophic triplet ring and a neutrosophic triplet ...

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

FEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,
