Provided herein are reactive aromatic molecules (e.g., substituted chrysene heterodimers) encodable as base-four sequences for the design and integrated synthesis of nucleic acids (e.g., DNA, RNA, hybrid DNA / RNA) and associated phospholipid bilayers (e.g., cellular membranes). For example, 3,6,9,12-tetrasubstituted chrysene is coupled with 6,12-disubstituted chrysene through π-electron stacking to form a base-four heterodimer. The orientation of the ring structure of the tetrasubstituted chrysene in this heterodimer comprises a base-two (binary) structure and the relative alignment of the ring structure of the disubstituted chrysene to the tetrasubstituted chrysene comprises a second independent base-two (binary) structure. This collectively results in a base-four (quaternary) complex composed of four independent reaction environments. Methods of using and forming these molecules and systems associated therewith are also described.

For example, 3,6,9,12-tetrasubstituted chrysene is coupled with 6,12-disubstituted chrysene through π-electron stacking to form a base-four heterodimer. The orientation of the ring structure of the tetrasubstituted chrysene in this heterodimer comprises a base-two (binary) structure and the relative alignment of the ring structure of the disubstituted chrysene to the tetrasubstituted chrysene comprises a second independent base-two (binary) structure. This collectively results in a base-four (quaternary) complex composed of four independent reaction environments. Methods of forming the heterodimers (and conjugated systems) include coupling sidechains of ethoxylated alcohol by phosphorylation. This may result in phosphodiester linkages at the 6,12 positions and / or uncoupled phosphorylated sidechains of ethoxylated alcohol at the 3,9 positions of the reactive aromatic molecules.
