title: The Structural Origin of Electron Injection Enhancements with Fulleropyrrolidine Interlayers.
abstract: The orientation of the substituent groups in a new class of work function modification layers, based on functionalized fulleropyrrolidines, is measured and found to directly account for the sign of the work function change.
