Herein we describe the synthesis and characterization of the first platinum(IV) metal-organic cage [(MePt)(byp)](OTf) (), in which the organometallic moieties trimethylplatinum(IV) (PtMe) occupied the corners of a cubane structure and 4,4'-bipyridine ligands used as linkers. The first-principles density functional theory calculations showed that the highest occupied molecular orbitals were localized on the PtMe moieties, while the lowest unoccupied molecular orbitals were distributed on the organic linkers.

Enhancing Initial State Overlap through Orbital Optimization for Faster Molecular Electronic Ground-State Energy Estimation.
Phys Rev Lett

Quantum Lab, Boehringer Ingelheim, 55218 Ingelheim am Rhein, Germany.
The phase estimation algorithm is crucial for computing the ground-state energy of a molecular electronic Hamiltonian on a quantum computer. Its efficiency depends on the overlap between the Hamiltonian's ground state and an initial state, which tends to decay exponentially with system size. We showcase a practical orbital optimization scheme to alleviate this issue.

With the rapid development of thermally activated delayed fluorescence (TADF) materials, achieving efficient reverse intersystem crossing (RISC) to mitigate triplet-triplet annihilation has emerged as a prominent research focus. This study investigates five derivative molecules, featuring varied bridging atoms/groups (O, S, Se, -CH-), designed from the reported TADF molecule with through-space charge transfer (TSCT) properties. Utilizing time-dependent density functional theory coupled with a PCM solution model, their excited state behaviors were simulated in a toluene environment.

The design and synthesis of nonlinear optical (NLO) materials are rapidly growing fields in optoelectronics. Considering the high demand for newly designed materials with superior optoelectronic characteristics, we investigated the doping process of Group-IIIA elements (namely, B, Al and Ga) onto alkali metal (AM = Li, Na and K)-supported COLi (AM@COLi) complexes to enhance their NLO response. The AM-COLi complexes retained their structural features following interaction with the Group-IIIA elements.

Li-TFSI/t-BP is the most widely utilized p-dopant for hole-transporting materials (HTMs) in state-of-the-art perovskite solar cells (PSCs). However, its nonuniformity of doping, along with the hygroscopicity and migration of dopants, results in the devices that exhibit limited stability and performance. This study reports the use of a spherical anion of the p-dopant, regulated by its radius and shape, as an alternative to the linear TFSI- anion.

The rational design of efficient hydroxyl intermediate (*OH) adsorption catalysts for dopamine electrooxidation still faces a major challenge. To address this challenge, a CeO-loaded CuO catalyst inspired by the f-p-d orbital hybridization strategy is designed to achieve efficient *OH adsorption and improve dopamine oxidation. The experimental results and theoretical calculations demonstrate that the f-p-d orbital hybridization regulates the electron distribution at the Ce-O-Cu interface, which facilitates electron transfer and optimizes the adsorption of *OH, thereby promoting dopamine oxidation.
