Supplementary Information: To bend or not to bend - are heteroatom interactions within conjugated molecules effective in dictating conformation and planarity

Supplementary information for Materials Horizons paper on affect of heteroatom interactions on planarity. Investigation of the roles of heteroatoms (mainly nitrogen, the halogens and the chalcogens) in dictating the conformation of linear conjugated molecules and polymers through non-covalent intramolecular interactions. Whilst hydrogen bonding is a competitive and sometimes more influential interaction, we provide unambiguous evidence that heteroatoms are able to determine the conformation of such materials with reasonable predictability.
