The first experimental evidence of room-temperature magnetocaloric effect in fullerenes

N Basicity of Substituted Fullero[60]/[70]pyrrolidines According to DFT/TD-DFT Calculations and Chemical Thermodynamics

“…Fullerenes having unique photophysical and electrochemical properties are promising objects not only for fundamental science but also for a wide range of applied developments. The electrical, optical, mechanical, and magnetocaloric properties of fullerenes are the basis for their use as materials for electronics, , spintronics, nanotechnology, − organic solar cells, − and different kinds of biologically active compounds and drugs. , Fullerenes are tested and studied as components of various catalytic and initiating systems …”

“…Here we present the results on the acid–base behavior of pyridyl-substituted fullero[60]/[70]­pyrrolidines (Figure ) in the CF 3 COOH/CH 2 Cl 2 medium and in the gas phase. The applied properties of the studied fullerenes, namely, the magnetocaloric activity and the ability to self-assemble in systems with macro-heterocyclic compounds possessing the property of PET, were discovered previously. ,,, The basicity and acidity constants with respect to N heteroatoms, below called the basicity and acidity constants of substituted fullerenes, were determined using spectrophotometric titration with CF 3 COOH in CH 2 Cl 2 and quantum-chemical calculations, respectively. Their relationship with such an important parameter as total dipole moment (TDM) was obtained.…”
