the power conversion efficiencies of heterojunction OPV devices
without perturbing HOMO/LUMO energies or the electron mobility
of fullerene acceptors. Ultimately this strategy of synthetically
manipulating the dielectric properties of materials may lead to
single-component, non-excitonic OPV devices.

derivatives by measuring the current–voltage characteristics of
electron-only devices with the following architecture at room
temperature: Au/fullerene derivative/LiF/Al. The experimental
J–V curves show that current density quadratically depends on
the voltage, which is a characteristic behavior of space-charge
limited current (SCLC).24 The J–V curves of PTEG-1 and PTEG-2
are shown in Fig. S5 (ESI†) corrected for the built-in voltage of
Vbi = 0.5 V and 0.05 V, respectively.
We found similar values for the electron mobility of the
fullerenes with single and double TEG side chains (PTEG-1 and
PTEG-2), PCBM of B2 Â 10À7 m2 VÀ1 sÀ1 (Table 1). Thus, in
addition to the electro-optical properties of the molecules being
unaffected by inclusion of TEG chains, their bulk electron
mobility did not change with respect to that of the benchmark
fullerene derivative, PCBM.

In conclusion, we synthesized fullerene derivatives with dielectric
constants significantly higher than C60 and PCBM, without
negatively impacting molecular properties (optical absorption
and reduction potentials) as well as bulk properties (electron
mobility). Our strategy of increasing polarizability by including 15 N. Camaioni and R. Po, J. Phys. Chem. Lett., 2013, 4, 1821.

a wide range of organic solvents. This work is one of the first
