“…This exceptional ability stems from adapted enzymatic pockets, which geometrically constrain reactants and stabilize specific reactive intermediates by placing electron-donating/accepting residues nearby. Here we perform an abiotic electrophilic aromatic substitution reaction, which is directed precisely through space. …”

“…Bader charge analysis shows that with Pt on B-vacancies, the nanosheets serve as a Lewis acid to accept electrons from Pt, and on the contrary, when Pt sits on N-vacancies, the nanosheets act as a Lewis base for donating electrons to Pt. The overall-electronic effect demonstrates an electron-rich feature of Pt after assembling on hexagonal boron nitride nanosheets. …”

“…The solvated title compound, bis­[2,6-bis­(1-{[4-(di­methyl­amino)­phen­yl]imino-κN}eth­yl)pyridine-κN]nickel(II) dichloride–di­chloro­methane–water (1/2/2), [Ni(C(25)H(29)N(5))(2)]Cl(2)·2CH(2)Cl(2)·2H(2)O, represents a nickel(II) bis­(pyridine di­imine) complex with electron-donating di­methyl­amino­phenyl substituents. The complex crystallizes as a water/di­chloro­methane solvate with Z′ = 2, thus the asymmetric unit consists of two Ni(II) complex cations, four chloride anions, four adventitious water and four di­chloro­methane solvent mol­ecules. …”

“…By a specific molecular design consisting into a minimal overlap between the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) due to a spatial separation of the electron-donating and the electron-releasing parts, luminescent materials exhibiting small S(1)–T(1) energy splitting could be obtained, enabling to thermally upconvert the electrons from the triplet to the singlet excited states by reverse intersystem crossing (RISC). …”

“…In this study, we revealed a new approach for the development of new triplet–triplet annihilation (TTA) materials with highly efficient deep-blue fluorescence via the incorporation of a styrylpyrene core and an electron-donating group. The resulting deep-blue emitters (PCzSP, DFASP, and DPASP) exhibit intramolecular charge transfer emissions with remarkably high emission quantum yields. …”
