摘要

Abstract

The solventnatures are crucial to deeply reveal solution behavior of macromolecular chains

physical essence of condensed state structures formation of the film as well as the photoelectronic devices performance. Based on the second virial coefficient (A

)

effect of the synergistic action of solvents and external electric field on both solution behavior and the film’s condensed state structure for the semi-rigid conjugated polymer

poly[2-methoxy-5-(2'-ethylhexoxy)-1

4-phenylvinylene] (MEH-PPV) was investigated by dynamic/static light scattering

photoluminescence spectroscopy and transmission electron microscopy

etc

. It was found that although the MEH-PPV solutions with different solvents (toluene

chlorobenzene

chloroform and tetrahydrofuran) all could generate a response to the external electric field

the degree of response varied significantly with the change of solvent nature. Furthermore

ordered degree of the film from the solutions was also obviously different. The essential reason for this responsive difference was firstly revealed in the research

which actually depended on the degree of interaction between the solute and solvent

and this degree of interaction could be quantitatively described by the second virial coefficient (A

). The bigger the A

the stronger the interaction between solvent and solute in the solution

and the stronger the response to the external electric field. Further

under the induction of external electric field

chains aggregations with different sizes were formed accompanied by large-scale chains ordered structure in the solution. This ordered structure not only can effectively transfer to film prepared by the precursor solution but also is beneficial to enhance the carrier mobility and device efficiency of the photoelectronic film.
