“…The use of this method leads to the calculation of d i f e for the all considered electronic states. We note that the XMC-QDPT2 method was applied to investigation of electronic and magnetic properties of small and large molecules and led to a good agreement with the experimental measurements (Baryshnikov et al 2016;Valiev et al 2013Valiev et al , 2014Minaev et al 2015).…”

We calculated the cross sections of photolysis of OH, LiO, NaO, KO, HCl, LiCl, NaCl, KCl, HF, LiF, NaF, and KF molecules using quantum chemistry methods. The maximal values for photolysis cross sections of alkali metal monoxides are on the order of 10−18 cm2. The lifetimes of photolysis for quiet Sun at 1 astronomical unit are estimated as 2.0 × 105, 28, 5, 14, 2.1 × 105, 225, 42, 52, 2 × 106, 35 400, 486, and 30 400 s for OH, LiO, NaO, KO, HCl, LiCl, NaCl, KCl, HF, LiF, NaF, and KF, respectively. We performed a comparison between values of photolysis lifetimes obtained in this work and in previous studies. Based on such a comparison, our estimations of photolysis lifetimes of OH, HCl, and HF have an accuracy of about a factor of 2. We determined typical kinetic energies of main peaks of photolysis-generated metal atoms. Impact-produced LiO, NaO, KO, NaCl, and KCl molecules are destroyed in the lunar and Hermean exospheres almost completely during the first ballistic flight, while other considered molecules are more stable against destruction by photolysis.

“…Photophysical processes comprise transition probabilities or rate constants for transitions between molecular electronic states. 1,2 The ratio between the rate constants for the radiative and nonradiative electronic transitions provides information about the fluorescence and phosphorescence quantum yields, which are important for the design of light emitting diodes, 3,4 laser dye devices, 5,6 photodynamic therapy, 7,8 and for understanding physical and chemical processes in the atmosphere. 9 The gas-phase formation of low-volatility accretion products, which is a key process affecting aerosol concentrations of importance for the air quality and the climate, most likely involve intersystem crossings.…”

In the current study we demonstrate an application of four previously synthesized 1,7-diphenyl-substituted BODIPY species for inverted photovoltaic cells and for organic light-emitting devices (OLEDs). Depending on the type of substituents or annulation of the pyridone rings these dyes exhibit spectral properties in the full visible region up to the near-infrared wavelengths. All the studied compounds show very strong visible absorption that can be ascribed to the low lying LUMO levels making them electronically suitable as acceptors for many donor materials. The best fabricated inverted photovoltaic device based on the BODYPI-core derivatives demonstrates a power conversion efficiency equal to 1.36% which is close to previously published reports for related species. Two kinds of deep red OLEDs (doped and undoped) with narrow electroluminescence spectra (full width at half maximum up to 45 nm) have been fabricated. Maximum brightness of 3900 cd m À 2 and an external quantum efficiency by 2.3% were achieved for the best OLED structure.
