Solvent-tunable dipeptide-based nanostructures with enhanced optical-to-electrical transduction.

We explore a facile approach to construct dipeptide-based building blocks containing π-conjugated bridges by using biocross-linkers. Well-defined nanostructures can be assembled and tuned by using different solvents. Compared to pristine units, such dipeptide-based assemblies exhibit structure-dependent and remarkably enhanced optoelectronic properties.
