“…Log K values fall in range from 4.11 to 5.25 l/mol for the studied humic substances and fullerene. The observed log K b values for the interaction between fullerene and studied humic acids are similar to the values found in previous study (log K b = 3.85-4.82 l/mol) using soil humic acid and polycyclic aromatic compounds [15] and also interaction between fullerene and cryptophanes shows log K values from 4.93 to 5.93 l/mol [31]. Strong binding is found to occur in the case of the interaction between Gagu bog HA and fullerene.…”

Interaction between buckminsterfullerene and humic substances of different origin was investigated using fluorescence spectrometry as function of concentration of humic substances, pH and ionic strength. Binding constants of humic substances and buckminsterfullerene were calculated. It can be suggested that the complexation was driven by hydrophobic interaction depending on properties of the interacting compounds. Hydrophobic interaction model was indicated by linear Stern-Volmer plot, and high K d values characterized interaction between buckminsterfullerene and humic acids. The results of this study support the development of understanding of fate of nanomaterials in environment as well as development of analytical techniques for nanomaterials in water and wastewater treatment approaches.

“…However, for interaction between fullerene (C 60 ) and cryptophanes A and E, linear Stern-Volmer plots are characteristic, and similar to our study fluorescence of the studied substance is quenched by fullerene. It is suggested that fullerene may interact with natural organic matter due to the hydrophobic interaction model [31,32].…”

The interaction between buckminsterfullerene C60 and humic acids (HA) of different origins was compared using fluorescence spectroscopy as a function of pH, humic acid concentration, ionic strength. Binding constants between fullerene and humic acids were calculated. It can be suggested that the complexation was driven by hydrophobic interactions depending on the properties of the interacting compounds. Hydrophobic interaction model as indicated by linear Stern-Volmer plots and high Kd values is characterizing the interaction between buckminsterfullerene C60 and humic acids The results of this study support the development of an understanding of the fate of nanomaterials in the environment as well as the development of analytical methods for nanomaterials in waters and wastewater treatment approaches.

“…Fullerene C60 is inclined to form of charge-transfer complexes with organic molecules [12]- [14]. The complexes are characterized a Ferster energy transfer from donor molecule (in our case, fluorophore molecule) to acceptor molecule (fullerene) with following fast oscillating (notably, nonradiative) relaxation [15].…”

Hybrid nanostructures including modified fullerene C60 and fluorophoric (E)-2-Cyano-3-(9-ethyl-9Н-carbazole-3-yl)-acrylic acid (cyanoacrylic acid I) were created. Spectral properties (absorption and luminescence spectra) of the hybrid nanostructures were investigated. It was established what molecules C60 strongly affected spectral properties of cyanoacrylic acid I in the hybrid nanostructures. Luminescence quenching of fluorophore and a change of luminescence features were observed in the hybrid nanostructures.
