Journal ArticleDOI
Room-temperature phosphorescence from organic aggregates
TL;DR: In this article, the authors analyzed key photophysical processes related to triplet excitons, including intersystem crossing, radiative and non-radiative decay, and quenching processes.
Journal ArticleDOI
Intramolecular electronic coupling for persistent room-temperature luminescence for smartphone based time-gated fingerprint detection
TL;DR: In this article, the CzDPS [9-9′-(sulfonylbis(2,1-phenylene))bis(9H-carbazole)] was designed and synthesized, which could emit persistent luminescence in crosslinked polymers with a doping concentration of only 1 wt%.
Journal ArticleDOI
Reversible Multilevel Stimuli-Responsiveness and Multicolor Room Temperature Phosphorescence Emission Based on a Single-Component System.
TL;DR: In this article , the authors reported the conversion of organic single-component small molecule 1,2-bis (4-alkoxyphenyl) ethane-1, 2-dione (N-BOX) with multilevel stimuli-responsiveness between high-efficiency blue and yellow RTP by grinding or thermal annealing N-BOX crystal.
Journal ArticleDOI
Small-molecule based thermally activated delayed fluorescence materials with dual-emission characteristics
TL;DR: In this paper, the authors summarized the design principles as well as the luminescence mechanism of organic donor-acceptor TADF compounds with dual-emission characteristics, the superiority of which can cover unique material applications in modern luminecence-related fields.

Density‐functional thermochemistry. III. The role of exact exchange
TL;DR: In this article, a semi-empirical exchange correlation functional with local spin density, gradient, and exact exchange terms was proposed. But this functional performed significantly better than previous functionals with gradient corrections only, and fits experimental atomization energies with an impressively small average absolute deviation of 2.4 kcal/mol.
Journal ArticleDOI
Development of the Colle-Salvetti correlation-energy formula into a functional of the electron density
TL;DR: Numerical calculations on a number of atoms, positive ions, and molecules, of both open- and closed-shell type, show that density-functional formulas for the correlation energy and correlation potential give correlation energies within a few percent.

Highly efficient phosphorescent emission from organic electroluminescent devices
Marc A. Baldo,D. F. O’Brien,Yujian You,Andrei Shoustikov,Scott Sibley,Scott Sibley,Mark E. Thompson,Stephen R. Forrest +7 more
TL;DR: In this article, a host material doped with the phosphorescent dye PtOEP (PtOEP II) was used to achieve high energy transfer from both singlet and triplet states.
Journal ArticleDOI
Density-Functional Theory for Time-Dependent Systems
Erich Runge,E. K. U. Gross +1 more
TL;DR: In this article, a time-dependent version of density functional theory was proposed to deal with the non-perturbative quantum mechanical description of interacting many-body systems moving in a very strong timedependent external field.

Highly efficient organic light-emitting diodes from delayed fluorescence
Hiroki Uoyama,Kenichi Goushi,Kenichi Goushi,Katsuyuki Shizu,Hiroko Nomura,Chihaya Adachi,Chihaya Adachi +6 more
TL;DR: A class of metal-free organic electroluminescent molecules in which the energy gap between the singlet and triplet excited states is minimized by design, thereby promoting highly efficient spin up-conversion from non-radiative triplet states to radiative singlet states while maintaining high radiative decay rates.
