A protocol for the synthesis of pyrrolo-p-phenylene-linked porphyrin-fullerene dyads suitable as photoactive materials was developed. The sequence of aziridination – aziridine ring opening – 1,3-dipolar cycloaddition reactions enabled us to provide structural variability both to the porphyrin core and to pyrrole linker, which facilitates designing the electronic structure and morphological parameters
Stereoselective synthesis of cis- and trans-2′,5′-disubstituted N-arylpyrrolo[3′,4′:1,9](C60-I h )[5,6]fullerenes by the 1,3-dipolar cycloaddition of azomethine ylides from dialkyl aziridinedicarboxylates to fullerene C60

2′,5′-disubstituted N-arylpyrrolofullerenes from anilines, alkyl glyoxylates, alkyl diazoacetates, and fullerene C60 was proposed. The key step of the synthesis is the 1,3-dipolar cycloaddition reaction of fullerene with azomethineylides generated by heating of dialkyl aziridinedicarboxylates. The thermal opening of the aziridine ring to azomethineylide and the cycloaddition of the latter to C60 at
