Conjugated Microporous Poly(Benzochalcogenadiazole)s for Photocatalytic Oxidative Coupling of Amines under Visible Light.

ChemSusChem 8 , 3459-64, (2015)

Metal-free visible-light photocatalysts offer a clean, sustainable solution to many pressing environmental issues. Herein, we present a molecular design strategy to fine-tune the valence and conductio...

Solar cell efficiency, self-assembly, and dipole-dipole interactions of isomorphic narrow-band-gap molecules.

J. Am. Chem. Soc. 134(40) , 16597-16606, (2012)

We examine the correlations of the dipole moment and conformational stability to the self-assembly and solar cell performance within a series of isomorphic, solution-processable molecules. These charg...
