AI Article Synopsis

  • The study examines a mechanochemical reaction involving [60]fullerene and various 3-benzylidene succinimides and related compounds using an inorganic base, conducted without solvents and via ball milling.
  • This method yields multiple [60]fullerene-fused cyclopentanes quickly and efficiently, demonstrating a wide range of substrate compatibility and minimal reaction time.
  • The resulting fullerene products have shown effectiveness as cathode interlayers in inverted planar perovskite solar cells, highlighting their potential in renewable energy applications.

Article Abstract

The mechanochemical cascade reaction of [60]fullerene with 3-benzylidene succinimides, diethyl 2-benzylidene succinate, or 2-benzylidene succinonitrile in the presence of an inorganic base has been investigated under solvent-free and ball-milling conditions. This protocol provides an expedient method to afford various [60]fullerene-fused cyclopentanes, showing advantages of good substrate scope, short reaction time, and solvent-free and ambient reaction conditions. Furthermore, representative fullerene products have been applied in inverted planar perovskite solar cells as efficient cathode interlayers.
