AI Article Synopsis
- Two types of fullerene derivatives were created to investigate how substituents affect the structure and photoelectrochemical properties of fullerene clusters on SnO(2) electrodes.
- Larger substituents on C(60) were found to increase cluster sizes while decreasing photon-to-current efficiencies due to steric hindrance.
- The study suggests that a C(60) molecule with two alkoxy chains can form a bilayer vesicle structure, providing insights for designing efficient photoactive molecules for energy conversion.
Article Abstract
Two kinds of fullerene derivatives have been designed to examine the effect of the fullerene substituents on the structure and photoelectrochemical properties of fullerene clusters electrophoretically deposited on nanostructured SnO(2) electrodes. The cluster sizes increase and the incident photon-to-current efficiencies decrease with introduction of large substituents into C(60). The trend for photocurrent generation efficiency as well as surface morphology on the electrode can be explained by the steric bulkiness around the C(60) molecules. A C(60) molecule with two alkoxy chains is suggested to give a bilayer vesicle structure, irrespective of the hydrophobic nature of both the C(60) and alkoxy chain moieties. Such information will be valuable for the design of photoactive molecules, which are fabricated onto electrode surfaces to exhibit high energy conversion efficiency.

The contact interface between the charge transport interlayer and the active layer is crucial for the non-fullerene organic solar cells (NF OSCs) to achieve high efficiency and long-term stability. In this study, two novel phenanthroline (Phen) derivatives, tbp-Phen and tbp-PhenBr, are developed as efficient cathode interfacial materials (CIMs). The larger steric hindrance substituents and the ionization of nitrogen atoms on the Phen framework jointly enable the tbp-PhenBr CIM with a stable film morphology and immensely suppress the detrimental interface chemical interactions with the NF active layer.

Article Synopsis
- The demetallation and remetallation of sulfanyl magnesium(II) porphyrazine with manganese(II) salts produce a novel manganese(III) derivative (Pz3), which was characterized using various spectroscopy techniques.
- Electrochemical testing showed that Pz3 has notable activity, especially when combined with multiwalled carbon nanotubes (MWCNTs), leading to improved detection of hydrogen peroxide (HO) compared to other electrode configurations.
- A biosensing platform for glucose detection was developed by integrating a glucose oxidase enzyme with the modified electrode, resulting in effective glucose readings in a linear range from 0.2 to 3.7 mM.

Evaporable indano[60]fullerene ketone (FIDO) was converted to indano[60]fullerene thioketone (FIDS) in high yield by using Lawesson's reagent. Three compounds with different substituents in position were successfully converted to the corresponding thioketones, showing that the reaction tolerates compounds with electron-donating and electron-withdrawing substituents. Computational studies with density functional theory revealed the unique vibrations of the thioketone group in FIDS.
