Article Abstract
A novel molecular platform characteristic of multiple transition metals (CH─Zn, CH─Ni, CH─Pt) on conjugated backbones is first established as high-performance electron acceptors. The CH─Pt-based ternary organic photovoltaics render an excellent power conversion efficiency surpassing 20%, more importantly, the unexplored dependency of central metals on intrinsic physicochemical properties of acceptors, nanoscale morphologies of donor/acceptor blends and final photovoltaic outcomes is fully disclosed. By demonstrating such a rare case of metal-containing acceptor, our work provides insight into whether metal complexes can serve as the building blocks of high-performance acceptors and gives guidance to rational design of metal-containing acceptors.

ConspectusMolecular photochemistry, by harnessing the excited states of organic molecules, provides a platform fundamentally distinct from thermochemistry for generating reactive open-shell or spin-active species under mild conditions. Among its diverse applications, the resurgence of the Minisci-type reaction, a transformation historically reliant on thermally initiated radical conditions, has been fueled by modern photochemical strategies with improved efficiency and selectivity. Consequently, the photochemical Minisci-type reaction ranks among the most enabling methods for C()-H functionalizations of heteroarenes, which are of particular significance in medicinal chemistry for the rapid diversification of bioactive scaffolds.

The nanoscale environment within the void spaces of metal-organic frameworks (MOFs) can significantly influence the photoredox catalytic activity of encapsulated visible-light photoredox catalysts (PCs). To compare two isostructural PC@In-MOF systems, three cationic Ru(II) polypyridine complexes were successfully encapsulated within the mesoscale channels of the anionic framework of InTATB (HTATB = 4,4',4''--triazine-2,4,6-triyltribenzoic acid), which features a doubly interpenetrated framework structure. This encapsulation yielded three heterogenized visible-light PCs, RuL@InTATB, where L = 2,2'-bipyridine (bpy), 1,10-phenanthroline (phen), or 2,2'-bipyrazine (bpz).

Donor-acceptor-donor (D-A-D) thiophene-based compounds, characterized by thiophene as a donor unit and benzothiadiazole (Bz) as an acceptor, represent an emerging class of theranostic agents for imaging and photodynamic therapy. Here, we expand this class of molecules by strategically varying the position of the electron-accepting unit within the oligothiophene (OT) backbone structure, realizing a series of different push-pull architectures (A-D, D-A-D, and D-A). This rational design allows for precise modulation of key photophysical parameters, including absorption and emission spectra, molar absorption coefficient, charge separation, and frontier molecular orbitals.

Alzheimer's disease (AD) is a neurodegenerative disease characterized by β-amyloid (Aβ) deposition, imposing significant social and economic burdens globally. Despite extensive efforts have been devoted to developing fluorescent probes for Aβ imaging, further improving the luminescent efficiency of prevailing probes still remains a significant challenge. Herein, we investigated the inner mechanism of constructing high-efficient Aβ probes via a structural cyclization strategy.

Electrochemical synthesis of ammonia (NH) is a promising green alternative to the conventional Haber-Bosch process. Here, we report the synthesis of a heteroatomic metal-metal bonded dual atomic (DA) Mn-Cu catalytic site embedded within nitrogen-doped carbon (NC) matrix for high-performance electrochemical reduction of N to NH. The asymmetric electronic distribution localized at the dual atomic sites synergistically enhances the adsorption and activation of N, facilitating the complex proton-coupled electron transfer process.
