Excited state kinetics in crystalline solids: Self-quenching in nanocrystals of 4,4′-disubstituted benzophenone triplets occurs by a reductive quenching mechanism
(American Chemical Society, 2011-11)
We report an efficient triplet state self-quenching mechanism in crystals of eight benzophenones, which included the parent structure (1), six 4,4′-disubstituted compounds with NH 2 (2), NMe 2 (3), OH (4), OMe (5), COOH ...
Properties of singlet- and triplet-excited states of hemicyanine dyes
(Versita, 2014-06)
The fluorescence emission spectra and fluorescence quantum yields of hemicyanine dyes LDS 698, LDS 722, and LDS 730 were measured in different media. No transient species was detected in the laser flash-photolysis experiments ...
Effect of Concentration on the Formation of Rose Bengal Triplet State on Microcrystalline Cellulose: A Combined Laser-Induced Optoacoustic Spectroscopy, Diffuse Reflectance Flash Photolysis, and Luminescence Study
(American Chemical Society, 2014-08)
Laser-induced optoacoustic spectroscopy (LIOAS), diffuse reflectance laser flash photolysis (DRLFP), and laser-induced luminescence (LIL) have been applied in conjunction to the determination of triplet state quantum yields ...
Optimized solution procedure of the G-particle-hole hypervirial equation for multiplets: Application to doublet and triplet states
(American Chemical Society, 2011-01)
Highly accurate descriptions of the correlated electronic structure of atoms and molecules in singlet states have recently been directly obtained within the framework of the G-particle-hole hypervirial (GHV) equation method, ...
Triplet state of 4-methoxybenzyl alcohol chemisorbed on silica nanoparticles
(Royal Society of Chemistry, 2012-06)
The knowledge of photochemical kinetics in colloidal systems is important in understanding environmental photochemistry on dispersed solid surfaces. As model materials for the chemically sorbed organic compounds present ...
Model studies on the photosensitized isomerization of bixin

On the efficacy of anthracene isomers for triplet transmission from CdSe nanocrystals
(Royal Society of Chemistry, 2017-01)
The effect of isomeric substitutions on the transmitter for triplet energy transfer (TET) between nanocrystal (NC) donor and molecular acceptor is investigated. Each isomeric acceptor is expected to bind in a unique ...
Exploring two-state reactivity pathways in the cycloaddition reactions of triplet methylene
(AMER CHEMICAL SOC, 2005-05-12)
Spin forbidden 1,2-cycloadditions of triplet methylene to alkenes have been theoretically studied as an example of the two-state reactivity paradigm in organic chemistry. The cycloadditions of triplet methylene to ethylene ...
