Abstract:
본 발명은 벤조싸이아다이아졸 유도체를 포함하는 발광 초분지 공액화 고분자에 관한 것으로, 벤조싸이아다이아졸계 단량체의 조성비 조절에 따라 다양한 색을 발광하는 것을 특징으로 하고 있다. 상기 발광 초분지 공액화 고분자는 초분지 형태를 이루고 있기 때문에 원하지 않는 에너지 전이를 최소화 할 수 있다. 또한, 본 발명에 따른 전기발광소자는 상기의 발광 초분지 공액화 고분자를 발광층으로 사용하였으며, 고분자 주쇄 내에 정공전달체를 포함하고 있기 때문에 정공전달층을 제외하고 전기발광소자를 제작한 것을 특징으로 한다. 상기 전기발광소자는 초분지 형태의 구조적 특성으로 인한 에너지 전이의 최소화를 바탕으로 단일 분자 백색 발광의 구현을 특징으로 한다.
Abstract:
The present invention relates to a light-emitting hyperbranched conjugated polymer containing a benzothiadiazole derivative which is illuminated with various colors according to the composition ratio modulation of benzothiadiazole-based monomers. The light-emitting hyperbranched conjugated polymer is able to minimize undesirable energy transfer since the light-emitting hyperbranched conjugated polymer has a hyperbranched form. The light emitting diode is manufactured without a hole transfer layer since the light-emitting hyperbranched conjugated polymer is used as a light-emitting layer, and a hole carrier is included in a polymer main chain. The light-emitting diode implements single molecule white light emitting based on the minimization of energy transfer due to the structural characteristic of the hyperbranched form.

CONSTITUTION: A manufacturing method of white luminescence nonwoven fabric comprises the following steps. a) Each spray solution is prepared by dissolving each of red, green, and blue light-emitting dyes and a transparent resin in a solvent; and b) the spray solutions prepared in the step a) are electrospun on a collector from different nozzles, each respectively, through an electrospinning device when a voltage is applied thereto. A light-emitting wave range of the red light-emitting dye is from 580 nm to 650 nm, the green light-emitting dye is from 480 nm to 550 nm, and the blue light-emitting dye is from 390 nm to 450 nm. A weight ratio of the red light-emitting dye : the green light-emitting dye : the blue light-emitting dye is 0.07375 to 0.0765 : 0.041 to 0.04375 : 0.8825 to 0.88525.
