“…Anthracene is an attractive building block for the design of fluorescent materials. 44 Besides the intense fluorescence in dilute solution, its excimer/exciplex existing in highly concentrated solutions and aggregation states exhibits red-shifted photoluminescence associated with exciton delocalization among two or more molecules. In 2020, Stoddart and co-workers obtained exciplex photoluminescence from permanent structures 12 8+ by incorporating anthracene moieties into mechanically interlocked molecules (Fig.…”

“…Singlet and triplet excitons are formed under the applied voltage in the ratio of 1 to 3 due to spin statistics [ 3 ]. The radiative deactivation of triplet excitons via phosphorescence involves a transition to the ground state of different multiplicity making the transition forbidden from the point of view of quantum mechanics [ 4 ]. The stimulation of phosphorescence in OLEDs was achieved by the application of noble metal complexes as emitters [ 5 , 6 ].…”

Two derivatives of phenyl pyrimidine as acceptor unit and triphenylamino or 4,4′-dimethoxytriphenylamino donor groups were designed and synthesized as emitters for organic light-emitting diodes (OLEDs) aiming to utilize triplet excitons in the electroluminescence. Thermogravimetric analysis revealed high thermal stability of the compounds with 5% weight loss temperatures of 397 and 438 °C. The theoretical estimations and photophysical data show the contributions of local excited and charge transfer states into emission. The addition of the methoxy groups led to the significant improvement of hole-transporting properties and the bathochromic shift of the emission from blue to green-blue spectral diapason. It is shown that mixing of the compounds with the organic host results in facilitation of the delayed emission. The singlet–triplet energy splitting was found to be too big for the thermally activated delayed fluorescence. No thermal activation of the long-lived emission was detected. No experimental evidence for triplet–triplet annihilation and room temperature phosphorescence were detected making the hot exciton mechanism the most probable one. The OLEDs based on the compounds reached the maximum external quantum efficiency of up to 10.6%.

The rising application of conventional synthetic insecticides develops resistant populations of houseflies; therefore, using new chemical agents with different modes of action is essential to overcome this problem. The mechanical grinding technique was used as a green method, to synthesize the tested compounds because it is a more facile work‐up and high‐yield economy, simplicity and solvent‐free than conventional thermal technique. Various methods were employed to synthesize new heterocycles containing anthracene (a photosensitizing agent) from chalcone 3, a building block material such as the preparation of the pyrazole derivatives 4–7, isoxazole derivative 8, pyrimidines 9–11, and oxirane derivative 12. The novel synthesized compounds were analyzed by FT‐IR, 1H‐NMR, 13C‐NMR spectra, and elemental analysis. Herein, the toxicity of the anthracene derivatives was assessed against Musca domestica larvae and adults in different conditions to demonstrate the effect of various inserted moieties on the efficiency of tested compounds. Furthermore, the influence of sunlight on the toxicity of anthracene was studied in dark and sunlight tests against adult houseflies. Moreover, these compounds diminished the total protein and lipids contents while significantly influencing the antioxidant enzymes activities of M. domestica adults. Structure‐activity relationships demonstrated the role of each moiety on the toxicity of compounds.
