Description

technical field

[0001] The invention belongs to the field of organic semiconductor optoelectronic materials, and in particular relates to a trimerindole-based hyperbranched conjugated polyelectrolyte and its preparation method and application. Background technique

[0002] Organic semiconductor materials have attracted extensive attention due to their advantages of light weight, low cost, flexibility, and large-area devices that can be prepared by solution processing, and have great application prospects. In the past ten years, as two important applications of organic semiconductor optoelectronic materials, organic light-emitting diodes (OLEDs) and organic solar cells (OPVs) have achieved important development. In these two types of devices, the interfacial layer plays an important role in improving the device performance. The interfacial layer includes a hole-transport layer and an electron-transport layer, which facilitate the ohmic contact between the corresponding elect...
