Summary: The meso-unsubstituted expanded porphyrinoid 3 is an effective ligand for Co(II) and can form metal-to-ligand metallocage complexes or metalloring species. Additionally, studies suggest that the Pd(II) complex is more stable compared to its Co(II) and Zn(II) congeners based on structural, electrochemical, and spectral analyses.

Summary: The study investigates the hydrogenation and dehydrogenation processes of two-dimensional materials on Pt(111), revealing selective hydrogenation of graphene (Gr) domains at low hydrogen coverage and thermal hydrogen release from hexagonal boron nitride (h-BN) domains at near room temperature. The presence of coexisting hydrogenated h-BN domains destabilizes C-H bonds in Gr, making H2 thermal release from Gr domains easier compared to a full graphene monolayer.

Summary: In this study, we demonstrate that the introduction of sulfur atoms induces an electronic structure modulation of SnO2 and its synergism with hexagonal boron nitride (hBN). The S-SnO2/S-hBN catalyst exhibits outstanding performance for the electrochemical detection of the toxic insecticide bendiocarb (BDC). The sulfur atoms act as electron acceptors, promoting electron transfer for the electrochemical process and enabling remarkable detection sensitivity and selectivity for BDC.

Summary: The internal strain and mass of metallofullerenes can be controlled to regulate the coupling and relaxation of magnetization in Dy-metallofullerenes. Mixed-metal nitride clusterfullerenes were synthesized and characterized, and magnetic studies revealed that the relaxation of magnetization correlated with the mass of the metal element. Ab initio calculations predicted different vibrational spectra of these compounds, leading to variations in relaxation.

Summary: Photothermal therapy (PTT) using near-infrared-II (NIR-II) light is an effective tumor therapy technique with deeper tissue penetration and higher laser power density. Black phosphorus (BP) has potential applications in PTT, but its low stability and limited photothermal conversion efficiency pose challenges. In this study, fullerene covalently modified few-layer BP nanosheets (BP-ester-C60) were developed to enhance stability and photothermal conversion efficiency.

In this study, a cadmium sulfide (CdS) interfacial engineering method was used to enhance the performance of antimony trisulfide (Sb2S3) based solar cells. The CdS interfacial layer improved the charge collecting efficiency and resulted in a high open-circuit voltage (V (oc)) of 0.76 V, the highest among solution-processed Sb2S3 solar cells.

Summary: The research interest in azulene-embedded polycyclic aromatic hydrocarbons (PAHs) has recently increased. However, the lack of efficient synthetic strategies hinders the investigation of their structure-property relationships and further opto-electronic applications. We report a modular synthetic strategy for diverse azulene-embedded PAHs, which includes non-alternant thiophene-rich PAHs, butterfly- or Z-shaped PAHs bearing two azulene units, and the first example of a two-azulene-embedded double [5]helicene.

Summary: The photoluminescent properties of photoluminescent metallofullerenes (EMFs) encapsulating photoluminescent lanthanide ions like erbium (Er) have been investigated. By entrapping an Er-cyanide cluster into various C82 cages, Er-monometallic cyanide clusterfullerenes (CYCFs) with photoluminescent properties are formed. It is found that the optical bandgap can be used to determine the photoluminescence of Er-EMFs, and the bandgap threshold is between 0.83 and 0.74 eV. The position of the Er atom within the C82 cage is fixed and independent of the endo-unit, suggesting that the previous statement on the role of metal position in photoluminescence is erroneous.

Summary: In this study, the electronic structures at the interface between CH3NH3PbI3 and C-60 with and without the modification of PbI2 were comprehensively studied using in situ photoemission spectroscopy measurements. The results showed that the addition of PbI2 improves charge carrier transport and slows down carrier recombination in perovskite solar cells (PSCs). However, PbI2 modification undermines device stability due to aggravated iodide migration.

Summary: A copolymer donor PBDTTPTP based on a tetracyclic bislactone unit, thieno[2',3':5,6]pyrano[3,4-d]thieno[3,2-b]pyran-4,9-dione (TPTP), was developed. The copolymer PBDTTPTP showed a deep HOMO level of -5.60 eV, a small optical bandgap of 1.65 eV and a good hole mobility of 6.57 x 10(-4) cm(2) V-1 s(-1) due to the strong electron-withdrawing properties and good coplanarity of TPTP. STOPVs based on PBDTTPTP and N3 exhibited a high light utilization efficiency of 4.38%, a power conversion efficiency of 12.26%, and an average visible light transmittance of 35.7%.
