Peptide-directed assembly of functional supramolecular polymers for biomedical applications: electroactive molecular tongue-twisters (oligoalanine-oligoaniline-oligoalanine) for electrochemically enhanced drug delivery
We report the preparation and characterization of films of electroactive supramolecular polymers based on non-electroactive oligoalanines and electroactive oligoanilines. Fibroblasts adhered to and proliferated on the films, and the delivery of the clinically relevant anti-inflammatory drug dexamethasone phosphate could be enhanced upon the application of an electrical stimulus.

Linear 1,4-coupled oligoanilines of defined length: Preparation and spectroscopic properties
A facile synthetic method involving SNAr coupling of 4-fluoronitrobenzene to arylamines, followed by reduction of the nitro groups, has been developed. The method allows the preparation of symmetric (NH 2/ NH2 end-capped) and asymmetric (Ph/NH2 end-capped) oligoanilines of even or odd chain lengths. The preparation of the NH2/NH2 end-capped trimer to octamer and Ph/NH2 end-capped trimer to pentamer is described. The effect of the chain length on the spectroscopic properties of the oxidized oligomers has been investigated by UV-Vis-NIR spectroscopy.

High-Pressure Synthesis of Oligoanilines
Aniline oligomers can be prepared cleanly and in high yield by the high-pressure promoted SNAr reaction of aromatic amines with fluoronitrobenzenes followed by reduction of the nitro group.
