Solubility of fullerene C(60) in 75 organic solvents was examined to develop quantitative structure-solubility relationships. Topological indices and polarizability parameter computed from refractive index were used to form the regression models. The models suggested for individual data sets such as alkanes, alkyl halides, alcohols, cycloalkanes, alkylbenzenes, and aryl halides have good predictive ability and are better than the models for the combined groups. Inclusion of an indicator parameter which is a combination of atom contributions and contributions of substituents' position in benzenes improved the predictive ability significantly.

Exploring potential third-order nonlinear optical (NLO) materials attracts ever-increasing attention. Given that the atomically precise and rich adjustable structural features of silver nanoclusters (Ag NCs), as well as the unique π-electron conjugated system of carbon-based nanomaterials, a supramolecular co-assembly amplification strategy to enhance the luminescent intensity and NLO performance of the hybrids of the two components, are constructed and the relationship between structures and optical properties are investigated. By combining water soluble Ag NCs [(NH)[Ag(mna)] (Hmna = 2-mercaptonicotinic acid, abbreviated to Ag─NCs hereafter) containing uncoordinated carboxyl groups with water-soluble fullerene derivatives modified with multiple hydroxyl groups (fullerenols, C─OH), the π-electron delocalization is expanded owing to non-covalent hydrogen bonding effect between Ag6─NCs and C─OH, which provides a feasible basis for realizing the NLO response.

Electrochemical polymerization of 3,4-ethylenedioxythiophene in the presence of water-soluble fullerene derivatives was investigated. The electronic structure, morphology, spectroelectrochemical, electrochemical properties and near-IR photoconductivity of composite films of poly(3,4-ethylenedioxythiophene) with fullerenes were studied for the first time. It was shown that fullerene with hydroxyl groups creates favorable conditions for the formation of PEDOT chains and more effectively compensates for the positive charges on the PEDOT chains.

Carbon nanotubes (CNTs) has emerged as a promising nanomaterial with a wide range of potential applications due to their unique structural, mechanical, electrical, and thermal properties. However, numerous obstacles must be overcome for CNTs to be used successfully, including low solubility, aggregation, and a lack of specialized functions. Diverse techniques have been developed for the manufacture, purification, and functionalization of CNTs in order to overcome these issues.

The shortwave infrared (SWIR) region is an ideal spectral window for next-generation bioimaging to harness improved penetration and reduced phototoxicity. SWIR spectral activity may also be accessed via supramolecular dye aggregation. Unfortunately, development of dye aggregation remains challenging.

Fullerenes (C, C) as carbon nanomaterials can enter the environment through natural processes and anthropogenic activities, while synthetic fullerenes are commonly used in medicine in targeted therapies in association with antibodies, or anticancer and antimicrobial drugs. As the nanoparticles, they can pass through cell membranes and organelles and accumulate in the entire cytoplasm. The red-fluorescent, water-soluble [70]fullerene derivative C-OMe-ser, which produces reactive oxygen species upon illumination with an appropriate wavelength, passed into the cytoplasm of the middle region in the digestive system.
