一般說明

2,3,5,6-四氟-7,7,8,8-四氰基喹二甲烷（F4-TCNQ）是一种用于制造有机半导体的掺杂剂。由于其最低的未占据分子轨道处于氧化多种半导体所需的理想能级，因此它可以调节电子特性。
2,3,5,6-四氟代-7,7,8,8-四氰基喹啉并二甲烷（F4-TCNQ）是p型分子，是强受主掺杂剂，它可产生自由空穴。

應用

F4-TCNQ可以掺入聚[双（4-苯基）（2,4,6-三甲基苯基）胺]（PTAA）以形成空穴传输材料（HTL），其可用于实现具有16%能量效率的半透明钙钛矿太阳能电池。它可以用作p型掺杂剂，与具有增强的电荷迁移率的聚（3-己基噻吩）（P3HT）形成混合复合膜，其可潜在用于有机光伏中。
F4-TCNQ是用于单空穴器件和具有有机空穴传输层（HTL）的场效应晶体管的p型掺杂剂。它用于制备F4-TCNQ和并五苯的双层结构，以研究改善有机薄膜的热电性能。

The chemical and structural origin of efficient p-type doping in P3HT

Molecular doping is a crucial tool for controlling the charge-carrier concentration in organic semiconductors. Each dopant molecule is commonly thought to give rise to only one polaron, leading to a maximum of one donor:acceptor charge-transfer complex and hence an ionization

Chemical treatment using bis(trifluoromethane) sulfonimide (TFSI) was shown to be particularly effective for increasing the photoluminescence (PL) of monolayer (1L) MoS2, suggesting a convenient method for overcoming the intrinsically low quantum yield of this material. However, the underlying atomic mechanism

Aharonov-Bohm oscillations effectively demonstrate coherent, ballistic transport in mesoscopic rings and tubes. In three-dimensional topological insulator nanowires, they can be used to not only characterize surface states but also to test predictions of unique topological behaviour. Here we report measurements

The electron acceptor F4TCNQ p-dopes aggregates "nanowires" of poly(3-hexylthiophene) in nonpolar solvents but does not dope unaggregated chains. The standard free energy change for the charge transfer to form an ion pair is ΔG°et = -0.21 eV. The dissociation constant

Metal-Organic Complexes for Doping Organic Semiconductors and Surface Doping

The conductivity of organic semiconductors can be increased, and the barriers to charge-carrier injection from other materials can be reduced, by the use of highly reducing or oxidizing species to n- or p-dope, respectively, the semiconductor.
