Abstract

Spin cast films of iptycene-derived aryleneethynylene polymers were synthesized and examined for their ability to detect electron deficient aromatics such as 2,4,6- trinitrotoluene and 2,4-dinitrotoluene. These polymers display a fast, reversible fluorescent response to vapors form these analytes, with the fluorescence attenuation dependent on the time of exposure of the films to the vapors. The iptycene-derived polymers have high fluorescence quantum yields in the solid state and display greater spectroscopic stabilities to heating and solvents than similar polyphenyleneethynylene polymers that lack rigid iptycene functionalities. The syntheses of these polymers will be discussed, as will their photophysical properties and response to different analytes.
