Photoluminescent energy transfer was investigated in conjugated polymer-fluorophore blended thin films. A pentiptycene-contg. poly(phenyleneethynylene) was used as the energy donor, and 13 fluorophores were used as energy acceptors. The efficiency of energy transfer was measured by monitoring both the quenching of the polymer emission and the enhancement of the fluorophore emission. Near-IR emitting squaraines and terrylenes were identified as excellent energy acceptors. These results, where a new fluorescent signal occurs in the near-IR region on a completely dark background, offer substantial possibilities for designing highly sensitive turn-on sensors.
