Vibration-mediated SOC has been suggested to explain this discrepancy, and also to facilitate singlet-triplet conversion between states of similar orbital character18,29. Vibrational contributions from an additional, or ‘intermediate’, triplet state give rise to the ‘spin-vibronic mechanism’ for ...
The triplet state lifetime is 474 ns under anaerobic conditions. The emission is entirely quenched when complex (54) is adsorbed onto a nanocrystalline TiO2 film. The very efficient quenching of the emission of (54) was found to be due to the electron injection from the excited singlet/...

摘要: The resonance coherent anti-Stokes Raman scattenng spectra of chrysene in the first excited singlet and triplet state are generated. The observed differences in wavenumber and intensity point out a changed molecular structure in the excited electronic states....
Here, we report a straightforward synthetic and isolation method for synthesizing a nonalternant nanographene (1) with a triplet ground state. Moving beyond the classic m-xylylene scaffold for high-spin organic molecules, seven-five-seven (7–5–7)-membered rings are introduced to create stable ...
A material possessing a very small energy gap between its singlet and triplet excited states,ΔE13, which allows efficient up-conversion of triplet excitons into a singlet state and leads to efficient thermally activated delayed fluorescence (TADF), is reported. The compound, 2-biphenyl-4,6-bis...
etc. Though discovery of Higgs boson was a direct proof of the role of a scalar in electro-weak symmetry breaking (EWSB) the existence of other Higgs multiplets cannot be ruled out. Recent studies also show that SM stands in a metastable state [5] and need other scalar to make the elec...
