【Abstract】 Poly(p-phenylenevinylene) and its derivatives are widely used in the organic light-emitting diodes,la- ser devices and photodetectors.The different defects in the ploy(p-phenylenevinylene) prepared by the Gilch method have a great influence on the photoelectric properties of materials and devices.In this paper the method that control the amount of gel and tolane -bisbenzyl is introduced.The molecular weight of the ploy(p-phenylenevinylene) has a influ- ence on the wavelength,so in this paper the factors which influence the molecular weight of ploy(p-phenylenevinylene) are also discussed.更多还原
