Conventional solution polycondensation of adipoyl chloride with ethidium bromide provided a new polyamide containing ethidium bromide in a polymer main chain. The polyamide was characterized by TGA, DSC, solubility, and absorption and fluorescent spectroscopy. A Good optical-quality film was obtained from HFIP solution of the polyamide. The polyamide showed blue-shift in the absorption band and high fluorescent intensity compared with ethidium bromide.
