摘要：

A new luminescent polymer, F-PTCD, with N,N '-bis-(propenyl aniline)- 3,4,9, 10-perylene tetracarboxylic diimide-emitting segments (PTCD) and 9,9-diphenylfluorene (DIPT) was synthesized by Heck reaction. The structures were characterized by MS, EA, H-1 NMR, IR and the photoluminescent (PL) properties were investigated by UV/vis absorption and fluorescence emission spectra. The fluorescence quantum yield was 0.453 in acetone. Thermogravimetric analysis and differential scanning calorimetry showed that the polymer is thermal stable up to 569 degrees C with glass-transition temperature higher than 125 degrees C. They are yellow-red emitting materials with the band gap of 2.33 eV estimated from the onset absorption. In addition, the emission can be quenched by both electron donor (N,N-dimethylaniline) and electron acceptor (Fullerene), where the processes followed the Stern-Volmer equation. Furthermore, the interaction between F-PTCD and carbon nanotubes (CNTs) was also studied by fluorescent quenching. (c) 2005 Elsevier Ltd. All rights reserved.
