摘要

研究了不同质量浓度卟啉(TTP)掺杂的MEH-PPV的紫外吸收和荧光发射光谱。这种掺杂体系在膜中和氯仿溶液中的吸收光谱具有同样的行为

同时

在这两种情况下发现了MEH-PPV链的聚集

以及TTP在420 nm的吸收随掺入量的增加而增加。但是

膜的发射光谱与氯仿溶液中的有所不同。因TTP的吸收带与MEH-PPV发射带的重叠

在膜和氯仿溶液中的高浓度掺杂体系中存在从MEH-PPV到TTP的Frster能量转移

但是在高TTP掺杂下的氯仿溶液中能量转移导致MEH-PPV发射峰的劈裂

而当溶液被稀释时

这种现象消失

表明此时能量给体和受体的距离扩大

这种能量转移的速率为1×10

Abstract

The spectral properties of different mass percentages of the porphyrin(5

20-tetra-p-tolyl-21H

23H-porphine

TTP) doped poly (MEH-PPV) were studied by UV-Vis absorption and fluorescent emission spectra in this paper. The absorption spectra of the blended systems as both films and chloroform solutions show the same behaviors. Meanwhile

the aggregation of polymer chains for MEH-PPV was found under the both cases and the absorption of TTP at 420 nm increase with increasing TTP in the blends. However

the emission spectra from the films are different from those in chloroform solutions. Frster energy transfer from MEH-PPV to TTP occurs in the films and chloroform solutions. Moreover

the splits of emission peak of MEH-PPV induced by energy transfer in chloroform solutions with high TTP doping levels are observed. The phenomenon is disappeared when the solution is diluted

indicating an enlarged distance between the energy donor and acceptor at that time. Furthermore

the rate of energy transfer was obtained at 1×10
