Summary: A conjugated polymer ( P1 ) containing a pendant aldehyde was anodically prepared on ITO electrodes. Aminothiophenes could be captured by reacting with an aldehyde group located along the polymer backbone resulting in a robust azomethine bond. This was confirmed both spectroscopically and electrochromically. P1 undergoes absorbance and fluorescence bathochromic shifts when an aminothiophene is covalently linked to the aldehyde resulting from azomethine formation. Both the absorbance and fluorescence shifts are dependent on the aminothiophene used to form the azomethine bond.
