Modulating supramolecular helicity and electrical conductivity of perylene dyes through an achiral alkyl chain

Here we have shown that it is possible to modulate hydrophobic and hydrophilic interactions to further adjust the supramolecular helicity by changing the length of an alkyl chain. These modulated supramolecular interactions have been translated to and observed in electrical conductivity, and provide a new pathway to construct a high-performance nanodevice.
