- Synthesis, photophysical and electrochemical properties of novel carbazole-triazine based high triplet energy, solution-processable materials
-
A series of molecules; tBuCz1SiTrz, tBuCz2SiTrz and tBuCz3SiTrz, which contain carbazole unit as hole-transporting group (donor-D) and triazine unit as electron transporting group (acceptor-A) were synthesized and characterized as high-triplet energy (>2.9 eV), solution-processable bipolar emitting materials. The conjugation between the D-A groups was interrupted by using bulky tetraphenylsilane groups as spacer aiming to obtain large bandgap and high-triplet energy. The photophysical behaviors of the molecules were investigated by UV-Vis absorption, photoluminescence, phosphorescence, photoluminescence quantum yield and lifetime measurements. Solvent polarity effects were investigated on the intramolecular charge transfer (ICT) behaviour and large solvatochromic effect was observed with the increasing solvent polarity. Electrochemical properties were determined by cyclic voltammetry. All molecules showed oxidation bands arise from the carbazole groups. Reduction bands were originated from the triazine groups and the intramolecular charge transfer between D-A groups. Photophysical, electrochemical and computational characterizations addressed that tBuCz2SiTrz has the weakest ICT character, highest photoluminescence quantum yield (PLQY) and charge balance.

- Synthesis, Structure, Photoluminescence, and Electroluminescence of Four Europium Complexes: Fabrication of Pure Red Organic Light-Emitting Diodes from Europium Complexes
-
Four new europium complexes were prepared by treating europium(III) trifluoro(thenoyl)acetonate trihydrate with new tridentate ligands, based on dipyrazolyltriazine and utilized as emitting materials in electroluminescent devices. The complexes were characterized by elemental analysis, FTIR spectroscopy, UV/Vis spectrophotometry, and 1H NMR spectroscopy. The coordinated ligands serve as light-harvesting chromophores in the complexes, with absorption maxima in the range 334–402 nm [ε = (8.9–81.4) × 103 m–1 cm–1]. The ligands efficiently sensitize europium luminescence, with maximum quantum-yield (QLEu) and observed lifetime (τobs) values of 34 % and 600 μs in the solid state and 35 % and 528 μs in toluene, respectively. The radiative lifetimes of Eu (5D0) are in the range 1170–1281 μs and the ligand-to-metal energy-transfer efficiency (ηsens) is in the range 71–92 % for those complexes in the solid state and in the range 68–97 % for those in solution. Additionally, organic light-emitting diodes (OLEDs), which exhibited pure red emission, were fabricated with europium(III) complexes. It is shown that by modifying the [Eu(tta)3·3H2O] molecule with ancillary ligands, one can tune and control its electroluminescence spectra, along with its electrical properties, such as the current/voltage characteristics of OLED devices based on [Eu(tta)3(L)]. The best OLED presented a maximum luminance of 3156 cd/m2 and a maximum efficiency of 0.7 cd/A at an applied voltage of 8 V.

- Polymerizable UV absorbers for the UV stabilization of polyesters. I. Design, synthesis and polymerization of a library of UV absorbing monomers
-
UV stabilizers, such as Tinuvin 1577, are organic additives that are used in the polymer industry to suppress polymer photodegradation, however leaching of the stabilizers from polymers is a significant practical issue which limits the effectiveness of the stabilizers and restricts polymer lifetimes. Novel, polymerizable UV stabilizers were synthesised and copolymerized with bis(2-hydroxyethyl) isophthalate to yield poly(ethylene isophthalate) copolymers where the UV stabilizers are bound covalently into the polymer chains. This strategy prevents leaching of stabilizers from polymers over time, and is expected to lead to enhanced UV protection of polymers compared to the admixing of polymers with UV stabilizers of low molar mass.

- Crystal Structure and Subsequent Ligand Design of a Nonriboside Partial Agonist Bound to the Adenosine A2AReceptor
-
In this study, we determined the crystal structure of an engineered human adenosine A2A receptor bound to a partial agonist and compared it to structures cocrystallized with either a full agonist or an antagonist/inverse agonist. The interaction between the partial agonist, belonging to a class of dicyanopyridines, and amino acids in the ligand binding pocket inspired us to develop a small library of derivatives and assess their affinity in radioligand binding studies and potency and intrinsic activity in a functional, label-free, intact cell assay. It appeared that some of the derivatives retained the partial agonist profile, whereas other ligands turned into inverse agonists. We rationalized this remarkable behavior with additional computational docking studies.

-
In this study, synthesis, characterization and catalytic performance of a novel supramolecular photocatalytic system including palladium (II) encapsulated within amine-terminated poly (triazine-triamine) dendrimer modified TiO2 nanoparticles (Pd (II) [PTATAD] @ TiO2) is presented. The obtained nanodendritic catalyst was characterized by FT-IR, ICP-AES, XPS, EDS, TEM, TGA and UV-DRS. The as-prepared nanodendritic catalyst was shown to be highly active, selective, and recyclable for the Suzuki–Miyaura and Sonogashira cross-coupling of a wide range of aryl halides including electron-rich and electron-poor and even aryl chlorides, affording the corresponding biaryl compounds in good to excellent yields under visible light irradiation. This study shows that visible light irradiation can drive the cross-coupling reactions on the Pd (II) [PTATAD] @ TiO2 under mild reaction conditions (27–30?°C) and no additional additives such as cocatalysts or phosphine ligands. So, we propose that the improved photoactivity predominantly benefits from the synergistic effects of Pd (II) amine-terminated poly (triazine-triamine) dendrimer on TiO2 nanoparticles that cause efficient separation and photogenerated electron–hole pairs and photoredox capability of nanocatalyst which all of these advantages due to the tuning of band gap of catalyst in the visible light region.

- 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.

- A Sequential Suzuki Coupling Approach to Unsymmetrical Aryl s-Triazines from Cyanuric Chloride
-
A practical approach has been developed for efficient synthesis of unsymmetrical aryl s-triazines via highly selective sequential Suzuki coupling of cyanuric chloride (2,4,6-trichlorotriazine) with aryl or vinyl boronic or diarylborinic acids catalysed by 0.1–0.5 mol% Pd(PPh3)2Cl2 under mild conditions. The second and third Suzuki couplings for unsymmetrically trisubstituted aryl s-triazines could be more practically conducted in one-pot procedure. An electron-withdrawing conjugate group at phenyl ring of arylboronic acids was unexpectedly found to completely block the coupling while steric hindrance from an ortho electron-donating substituent could be overcome. (Figure presented.).
