Efficient Hydro- and Organogelation by Minimalistic Diketopiperazines Containing a Highly Insoluble Aggregation-Induced, Blue-Shifted Emission Luminophore**
We report the synthesis, gelation abilities and aggregation-induced, blue-shifted emission (AIBSE) properties of two minimalistic diketopiperazine-based gelators. Despite containing a highly insoluble luminophore that makes up more than half of their respective molecular masses, efficient hydrogelation by multiple stimuli for one and efficient organogelation for the other compound are reported. Insights into the aggregation and gelation properties were gained through examination of the photophysical and material properties of selected gels, which are representative of the different modes of gelation. The synthesis of the gelators is highly modular and based on readily available amino acid building blocks, allowing the efficient and rapid diversification of these core structures and fine-tuning of gel properties.

Discovery and mechanism of action studies of 4,6-diphenylpyrimidine-2-carbohydrazides as utrophin modulators for the treatment of Duchenne muscular dystrophy
Duchenne muscular dystrophy is a fatal disease with no cure, caused by lack of the cytoskeletal protein dystrophin. Upregulation of utrophin, a dystrophin paralogue, offers a potential therapy independent of mutation type. The failure of first-in-class utrophin modulator ezutromid/SMT C1100 in Phase II clinical trials necessitates development of compounds with better efficacy, physicochemical and ADME properties and/or complementary mechanisms. We have discovered and performed a preliminary optimisation of a novel class of utrophin modulators using an improved phenotypic screen, where reporter expression is derived from the full genomic context of the utrophin promoter. We further demonstrate through target deconvolution studies, including expression analysis and chemical proteomics, that this compound series operates via a novel mechanism of action, distinct from that of ezutromid.

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.

Trizaine-based dehydrative condensation reagents bearing carbon-substituents
Herein, we report on the synthesis of alkyl-, aryl-, and alkynyl-substituted chlorotriazines and their ammonium salts, and demonstrate their utility in dehydrative condensation reactions. Although the electrophilicity of these reagents is mainly dependent on the hybridization of the carbon-substituents, it was found that bulky 2,6-dimethylphenyl group-substituted reagents resulted in the highest product yields because of a slight increase in reagent electrophilicity and/or steric hindrance favorable for desired dehydrative condensation reactions.

A ternary phosphine oxide host featuring thermally activated delayed fluorescence for blue PHOLEDs with >20% EQE and extremely low roll-offs
Development of high-performance blue organic light-emitting diodes (OLEDs) is one of the main challenges because efficient host-dopant energy transfer is necessary to develop highly efficient OLEDs. In this study, an effective molecular design strategy for blue phosphorescent hosts with high triplet (T1) energy and the feature of thermally activated delayed fluorescence (TADF) has been demonstrated using a ternary donor-acceptor-acceptor (D-A-A) molecule, DCDPOTZ, in which carbazole, triazine and diphenylphosphine oxide are incorporated as donor and acceptors. DCDPOTZ achieves the typical characteristics of TADF with a high T1 energy level of 2.93 eV and a small singlet-triplet splitting of 0.27 eV, accompanied by the ambipolar property. Its host characteristics are further improved by its diphenylphosphine oxide group with large steric hindrance for suppressing intermolecular interaction-induced quenching. By adopting bis(4,6-difluorophenylpyridinato)tetrakis((1-pyrazolyl)borate)iridium(iii) (FIr6) as a dopant, DCDPOTZ successfully realizes 100% host-dopant energy transfer efficiency. As a consequence, DCDPOTZ endowed its FIr6-based devices with extremely low driving voltages, the state-of-the-art external quantum efficiency (EQE) of up to 22.7%, and 100% internal quantum efficiency. At 1000 nits, the EQE is still beyond 20%, corresponding to a roll-off as low as 11%, which is one of the lowest values reported to date for blue phosphorescent OLEDs.

Utilizing triazine/pyrimidine acceptor and carbazole-triphenylamine donor based bipolar novel host materials for highly luminescent green phosphorescent OLEDs with lower efficiency roll-off
In this work, two novel bipolar host materials were designed, synthesized and applied in green phosphorescent based OLEDs. Both the host materials, 4-(2-(4,6-diphenyl-1,3,5-triazin-2-yl)-9H-carbazol-9-yl)-N,N-diphenylaniline (TRZ 1) and 4-(2-(4,6-diphenylpyrimidin-2-yl)-9H-carbazol-9-yl)-N,N-diphenylaniline (PYR 1) exhibited high thermal stability, with decomposition temperatures of 425 °C and 400 °C, respectively. The triplet energy of PYR 1 (2.63 eV) was higher than that of TRZ 1 (2.44 eV), and facilitated suitable energy transfer to the green dopant. The PYR 1 based green device demonstrated an excellent maximum current efficiency of 48.7 cd/A and external quantum efficiency of 16.4%. Interestingly, the green device with PYR 1 showed an outstanding brightness of 95,870 cd/m2, which is three times greater than that of the reference CBP based device (31,370 cd/m2). The bipolar host PYR 1 is a promising material for high luminescent and low efficiency roll off applications, especially for green PhOLEDs.

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.

An Isolable and Bench-Stable Epoxidizing Reagent Based on Triazine: Triazox
A new triazine-based oxidizing reagent, 2-hydroperoxy-4,6-diphenyl-1,3,5-triazine (Triazox), has been developed. The reagent can be synthesized from inexpensive starting materials and is a bench-stable solid that is isolable in pure form. Epoxidation of alkenes possessing acid-sensitive functionalities using Triazox proceeded in good to excellent yields. The accompanying nonacidic triazinone coproduct can be easily removed by filtration. These features indicate that Triazox is a practically useful oxidizing reagent.
