AB  - Two different alpha,omega-diglicynes linked by linear polyoxaalkyl chains in the presence of formaldehyde underwent Prato reaction to the fullerene C-60. The shorter linker templated formation of only cis-bisadducts, while the longer one afforded a mixture of four bisadducts (all cis and the equatorial) and difullerene dumbbell compound. Their structures were confirmed by the extensive analysis of the spectral data and molecular symmetry, as well. All compounds expressed an ability to arrange into hierarchically ordered supramolecular aggregates, the form of which depended both on the addition pattern and the spacer structure. The attenuated electron-accepting affinity, examined by cyclic voltammetry was in agreement with diminished delocalization of the pi-electronic system. In addition, all compounds exerted a notable radical scavenging activity.

AB  - Four fullerosteroidal conjugates, previously confirmed to express two- to threefold better antioxidant activity in vitro than C-60, were subjected to additional studies, including electrochemical, theoretical, and morphological examination. All tested compounds underwent reversible, diffusion-controlled reductions. A notable influence of the solvent properties on the reduction potential, the level of aggregation, and the lowest unoccupied molecular orbital (LUMO) energy was observed. Theoretical calculations indicated that the energy gain obtained by an intermediate formation, together with compounds' polarizability, polarity, and lipophilicity contributed to the radical quenching capacity. Very large supramolecular aggregates of all fullerosteroidal esters with no hierarchical arrangement were observed in precipitated samples, while solvent induced self-assembling led to round nanoplates, which further arranged to flower-shaped hierarchically ordered architectures or uniformly distributed discoid particles. As in electrochemical studies, fine tuning of the aggregation level was achieved by the solvent.

AB  - A series of novel fulleropyrrolidine-phthalimide dyads was synthesized and their electrochemical and self-assembly properties were investigated. Efficient synthesis of acceptor-acceptor dyads was performed under microwave irradiation. Fine-tuning of the second redox potentials in the dyads was achieved by varying the length of the aliphatic spacer (C-2 to C-12) between the fulleropyrrolidine and phthalimide moieties. Shape-shifting and supramolecular polymorphism were observed for these compounds during self-assembly.
