Fluorescence Quenching Naphthalene Diimide Multimers with Siloxane Cores

Abstract

The hydrosilylation of a naphthalene diimide (NDI) to form three amorphous electron-accepting compounds with siloxane cores is presented. All three compounds successfully quench emissions from p-type polymers poly(3-hexylthiophene) (P3HT) and poly[2-methoxy-5-(3′,7′-dimethyloctyloxy)-p-phenylene vinylene] (MDMO-PPV). The work is an extension of their earlier report featuring a tetrameric NDI system with a tetrahedral tetraphenyl methane core (J. Am. Chem. Soc. 2005, 127, 14530).
