In this article Jagadeesh B. Bodapati and Huriye Icil from the Eastern Mediterranean University in Turkey report on the synthesis of an oligomer showing concentration and solvent dependent fluorescent colour tunability, which has potential in various photo-sensing applications.
The oligomer was synthesised in a one-step condensation reaction and contains flexible hydrophilic hexa(ethylene glycol) and hydrophobic naphthalene-bisimide chromophores. It showed strong solvent-dependent photophysical and electrochemical properties, including a large shift of excimer emission maximum reflecting self-assembly mediated through hydrogen bonding and π-stacking interactions.
