Research Progress in Tri(Pentafluorophenyl)Borane Doped Organic/Polymer Semiconductors
The structural design of organic/conjugated polymers is an effective strategy for the preparation of high-performance organic semiconductors.However,this process is associated with problems such as long design and synthesis cycles,complex preparation steps,and low yields.To overcome these issues,doping of organic/conjugated semiconductors has garnered increasing attention in recent years.However,traditional charge transfer dopants(such as elemental iodine,iron oxide Fe3O4,and small molecule F4TCNQ)suffer from low doping efficiency,poor solubility,and stringent doping conditions.In contrast,tri(pentafluorophenyl)borane offers advantages such as high solubility,high doping efficiency,and wide adaptability.This article combines relevant literature to review the physical mechanism of tri(pentafluorophenyl)borane doping in organic semiconductors and discusses the properties of doped organic semiconductors.Additionally,the applications of tri(pentafluorophenyl)borane doping in various optoelectronic functional devices are summarized.Finally,this article also points out future research directions,hoping to contribute to the study of doped organic semiconductor devices.
