Synthesis, Spectra, and Theoretical Investigations of 1,3,5-Triazines Compounds as Ultraviolet Rays Absorber Based on Time-Dependent Density Functional Calculations and three-Dimensional Quantitative Structure-Property Relationship
A series of 1,3,5-triazines were synthesized and their UV absorption properties were tested. The computational chemistry methods were used to construct quantitative structure-property relationship (QSPR), which was used to computer aided design of new 1,3,5-triazines ultraviolet rays absorber compounds. The experimental UV absorption data are in good agreement with those predicted data using the Time-dependent density functional theory (TD-DFT) [B3LYP/6–311 + G(d,p)]. A suitable forecasting model (R > 0.8, P 0.0001) was revealed. Predictive three-dimensional quantitative structure-property relationship (3D-QSPR) model was established using multifit molecular alignment rule of Sybyl program, which conclusion is consistent with the TD-DFT calculation. The exceptional photostability mechanism of such ultraviolet rays absorber compounds was studied and confirmed as principally banked upon their ability to undergo excited-state deactivation via an ultrafast excited-state proton transfer (ESIPT). The intramolecular hydrogen bond (IMHB) of 1,3,5-triazines compounds is the basis for the excited state proton transfer, which was explored by IR spectroscopy, UV spectra, structural and energetic aspects of different conformers and frontier molecular orbitals analysis.

Non-doped thermally activated delayed fluorescent organic light-emitting diodes using an intra- and intermolecular exciplex system with a: Meta -linked acridine-triazine conjugate
We report OLEDs utilizing non-doped TADF emitters, 10-(3-(4,6-diphenyl-1,3,5-triazin-2-yl)phenyl)-9,9-dimethyl-9,10-dihydroacridine (AmT) and 10-(3′-(4,6-diphenyl-1,3,5-triazin-2-yl)-[1,1′-biphenyl]-3-yl)-9,9-dimethyl-9,10-dihydroacridine (AmmT). These two emitters are composed of electron donor (acridine) and acceptor (triphenyltriazine) moieties, which are connected at the meta positions so that intra- and intermolecular charge transfer (CT) states can be induced through exciplex-like interactions between the same emitters. A neat film of AmmT forms intermolecular CT state-induced exciplexes more favorably than AmT because of the packing benefits and relatively shorter radiative lifetime of AmmT. Electroluminescent devices using AmmT as an emitter exhibit an external quantum efficiency (EQE) over 18%, which is much better than the EQE value for devices using AmT. This is the first example of a non-doped TADF system using a single molecule-based exciplex as a dominant exciton source.
