AI Article Synopsis
- Inorganic fullerene clusters are gaining interest due to their unique geometric shapes and electronic properties, but similar structures made from heavy metals are rare and hard to create.
- The study introduces a new cluster named [K(Bi@Pd@Bi)], which features a bismuth cage structure and is noted as the largest of its kind.
- Additional investigations reveal that this cluster exhibits a quartet spin state and shows electronic characteristics similar to carbon, along with a distinct open-shell aromatic property.
Article Abstract
Inorganic fullerene clusters have attracted widespread attention due to their highly symmetrical geometric structures and intrinsic electronic properties. However, cage-like clusters composed of heavy metal elements with high symmetry are rarely reported, and their synthesis is also highly challenging. In this study, we present the synthesis of a [K(Bi@Pd@Bi)] cluster that incorporates a {Bi} cage with - symmetry, making it the largest main group metal cluster compound composed of the bismuth element to date. Magnetic characterization and theoretical calculations suggest that the spin state of the overall cluster is a quartet. Quantum chemical calculations reveal that the [Bi] cluster has a similar electronic configuration to C and the [Bi@Pd@Bi] cluster exhibits a unique open-shell aromatic character.

Transdermal insulin delivery in a painless, convenient, and on-demand way remains a long-standing challenge. A variety of smart microneedles (MNs) fabricated by glucose-responsive phenylboronic acid hydrogels have been previously developed to provide painless and autonomous insulin release in response to a glucose level change. However, like the majority of MNs, their transdermal delivery efficiency was still relatively low compared to that with subcutaneous injection.

NHC-[60]fullereborane (NHC-BH-CH) has been synthesized, isolated in pure form, and characterized. The reaction of C with NHC-borane produced NHC-BH-CH as the first air-stable and separatable fullerene-borane compound. The formation of a N-heterocyclic carbene stabilized this borane complex of C, and the structure of the complex was unambiguously determined throughsingle-crystal X-ray analysis.

The DBU-promoted three-component coupling reaction of H-phosphonates, [60]fullerene, and alkyl bromides has been developed as a facile and efficient protocol for the one-pot synthesis of various 1,4-(phosphonyl)(organo)[60]fullerenes. This method exhibits high regioselectivity at the 1,4-position on the [60]fullerene core and features a metal-free nature, easy operation, low cost, and a wide range of substrates.

A novel isotropic fullerene-hybridized fused-ring electron acceptor, designated C-Y, has been synthesized via a mild [4+2] Diels-Alder cycloaddition reaction with fullerene C to enhance the performance of organic solar cells (OSCs). Comparative analysis shows that C-Y significantly outperforms the control acceptor Me-Y, with a notable increase in the relative dielectric constant from 2.79 to 3.
