Porous shape-persistent rylene imine cages with tunable optoelectronic properties and delayed fluorescence
<p>A simultaneous combination of porosity and tunable optoelectronic properties, common in covalent organic frameworks, is rare in shape-persistent organic cages. Yet, organic cages offer important molecular advantages such as solubility and modularity. Herein, we report the synthesis of a series of chiral imine organic cages with three built-in rylene units by means of dynamic imine chemistry and we investigate their textural and optoelectronic properties. Thereby we demonstrate that the synthesized rylene cages can be reversibly reduced at accessible potentials, absorb from UV up to green light, are porous, and preferentially adsorb CO<sub>2</sub> over N<sub>2</sub> and CH<sub>4</sub> with a good selectivity. In addition, we discovered that the cage incorporating three perylene-3,4:9,10-bis(dicarboximide) units displays an efficient delayed fluorescence. Time-correlated single photon counting and transient absorption spectroscopy measurements suggest that the delayed fluorescence is likely a consequence of a reversible intracage charge-separation event. Rylene cages thus offer a promising platform that allows combining the porosity of processable materials and photochemical phenomena useful in diverse applications such as photocatalysis or energy storage.</p>

Adsorption of N, He, and Ne on CGe nanoribbons for sensing and optoelectronic applications
<p>Research into nanomaterials yields numerous exceptional applications in contemporary science and technology. The subject of this investigation is a one-dimensional nanostructure, six atoms wide, featuring hydrogen-functionalized edges. The theoretical foundation of this study relies on Density Functional Theory (DFT) and is executed through the utilization of the Vienna Ab initio Simulation Package (VASP). The outcomes demonstrate the stability of adsorption configurations, along with the preservation of the hexagonal honeycomb lattice. The pristine configuration, characterized by a wide bandgap, is well-suited for optoelectronic applications, whereas adsorption configurations find their application in gas sensing. Nitrogen (N) adsorption transforms the semiconducting system into a semi-metallic one, with the spin-up state displaying semiconductor characteristics and the spin-down state exhibiting metallic attributes. The intricate multi-orbital hybridization is explored through the analysis of partial states. While the pristine system remains non-magnetic, N adsorption introduces a magnetic moment of 0.588 μ<sub>B</sub>. Examination of charge density differences indicates a significant charge transfer from N to the CGe substrate surface. Optical properties are systematically investigated, encompassing the dielectric function, absorption coefficient, and electron-hole density. Notably, the real part of the dielectric function displays negative values, a result that holds promise for future communication applications.</p>

Styrene monomer as potential material for functionalization and design of chromophores for new optoelectronic and NLO polymers conception: DFT study
<p>Using Density functional theory (DFT), we have studied the intrinsic properties of styrene. We determine firstly: optimized structures, structural parameters, and thermodynamic properties to make our simulations more realistic to experimental results and check the stability. We secondly investigate optoelectronic, electronic, and global descriptors, transport properties of holes and electrons, NBO analysis, absorption, and fluorescence properties. We finally study NLO:1st and 2nd order hyperpolarizability, 2nd and 3rd order optical susceptibilities, hyper-Rayleigh scattering hyperpolarizability, EOPE, DC-KERR effects, and quadratic refractive index. The bandgap energy E<sub>g</sub> = 5.146 eV and dielectric constant show that styrene is a good insulator with an average electric field value of 4.43×10<sup>8 </sup>Vm<sup>-</sup><sup>1</sup>. Thermodynamic findings show that our molecule is thermodynamically and chemically stable. Electron and hole reorganization energies of 0.393 eV and 0.295 eV, respectively, show that styrene is more favorable to hole transport than electron transport. Styrene is transparent with linear refractive index n = 1.750 and quadratic . At the NLO, styrene has a non-zero value of which confirms the existence of first-order nonlinear optical activity. Globally the study shows that the styrene monomer is suitable for the architecture design of new polymer materials for NLO applications and optoelectronic by functionalization.</p>
