Quantum chemistry simulations offer a cost-effective way to computationally design BODIPY photosensitizers. However, accurate predictions of excitation energies pose challenge for time-dependent density functional theory and equation-of-motion coupled-cluster singles doubles methods. By contrast, reliable can be achieved by multireference quantum methods; unfortunately, their computational cost increases exponentially with the number electrons. Alternatively, computing holds potential an exact simulation photophysical properties in more efficient way. Herein, we introduce state-specific ΔUCCSD-VQE (unitary doubles-variational eigensolver) ΔADAPT-VQE methods which electronically excited state is calculated via non-Aufbau configuration. We show six derivatives that proposed predict are good agreement those from experiments. Due its performance simplicity, believe ΔADAPT will become useful approach photosensitizers on near-term devices.

Substituting precious elements in luminophores and photocatalysts by abundant first-row transition metals remains a significant challenge, iron continues to be particularly attractive owing its high natural abundance low cost. Most complexes known date face severe limitations due undesirably efficient deactivation of luminescent photoredox-active excited states. Two new iron(III) with structurally simple chelate ligands enable straightforward tuning ground state properties, contrasting recent examples, which chemical modification had minor impact. Crude samples feature two luminescence bands strongly reminiscent complex, this observation was attributed dual luminescence, but our case, there is clear-cut evidence that the higher-energy stems from an impurity only red photoluminescence doublet ligand-to-metal charge transfer (2LMCT) genuine.

Photocatalysis holds great promise for changing the way value-added molecules are currently prepared. However, many photocatalytic reactions suffer from quantum yields well below 10%, hampering transition lab-scale to large-scale or even industrial applications. Molecular dyads can be designed such that beneficial properties of inorganic and organic chromophores combined, resulting in milder reaction conditions improved reactions. We have developed a novel approach obtaining advantages molecular without time- resource-consuming synthesis these tailored photocatalysts. Simply by mixing cationic ruthenium complex with an anionic pyrene derivative water salt bichromophore is produced owing electrostatic interactions.

Pendant organic chromophores have been used to improve the photocatalytic performance of many metal-based photosensitizers, particularly in first-row metals, by increasing π conjugation ligands and lowering energy photoactive absorption band. Using a combination spectroscopic studies computational modeling, we rationalize excited state dynamics Co(III) complex containing pendant pyrene moieties, CoL1, where L1 = 1,1′-(4-(pyren-1-yl)pyridine-2,6-diyl)bis(3-methyl-1H-imidazol-3-ium). CoL1 displays higher visible absorptivity, blue luminescence from singlet states compared with CoL0 [L0 1,1′-(pyridine-2,6-diyl)bis(3-methyl-1H-imidazol-3-ium)] which moiety is absent. Emissive properties are highly influenced metal center, reducing fluorescence lifetime 5.9 3.5 ns, shift 43 nm. The lower d orbitals Fe(II) drastically affects character state, resulting mixture intraligand charge-transfer (1ILCT) ligand-to-metal (1LMCT) character. Transient experiments revealed that although dark triplet (3ILPyrene) present, it not efficiently populated possesses short nanosecond-scale lifetime. Instead, metal-centered (3MC) dominate decay path 2.4 ps lifetime, no photoactivity toward oxygen formation or triplet–triplet transfer (TTET). This work shows how various factors can influence excited-state dynamics.

Hydrogenation of ketones, aldehydes, and imines plays an important role in organic synthesis due to the ubiquity alcohols amines complex molecules. The highly negative reduction potentials carbonyl compounds typically necessitate strong hydride reagents, high-pressure hydrogen gas, or UV light facilitate hydrogenation reactions. Visible-light photoreduction these substrates, a more recent development, usually results formation diol diamine products via dimerization ketyl iminyl radical intermediates. In this work, taking advantage hydricity 1,3-dimethyl-2,3-dihydro-2-phenylbenzimidazole (BIH) coupled with potent excited-state reducing power β-diketiminate-supported bis-cyclometalated iridium photosensitizer, we promote switch selectivity from hydrogenation.
