Tetrahedral <i>n</i>-Type Materials: Efficient Quenching of the Excitation of <i>p</i>-Type Polymers in Amorphous Films

Abstract

Tetrahedral naphthalenediimide compound 1 has been synthesized as an example of a new class of amorphous n-type materials, in which the nondirectionality obtained by its shape is decoupled from its optoelectronic properties. 1 forms bicontinuous films with p-type polymers and effectively quenches the excited state, yielding long-lived mobile charge carriers on pulsed illumination.
