可形成电荷转移（CT）复合物的添加剂可增强聚合物的光电导性。相比之下，含有此类添加剂的聚合物的暗电导率仅略有增加。几种结晶 CT 配合物表现出高暗电导率。当被引入到聚合物基质中时，只要 CT 复合物是有序的，这些聚合物就会显着提高其电导率，因为它们的高电导率与晶体中供体和受体堆叠之间的强相互作用有关。我们在这里描述了一种将微晶 CT 复合物引入聚合物的新方法。它由薄膜铸造过程中生长的微晶体组成。该系统由聚（双酚 A 碳酸酯）/（PC）和 7,78,8-四氰基醌二甲烷（TCNQ）与四硫并四苯（TTT）的 CT 络合物微晶组成，在室温下以络合物的 1 wt% 达到暗电导率 3 × 10−2Ω−1cm−1。该电导率仅轻微依赖于温度。
Additives which can form charge-transfer (CT) complexes enhance the photoconductivity of polymers. In contrast, the dark conductivity of polymers containing this type of additive increases only slightly. Several crystalline CT complexes exhibit high dark conductivity. When introduced into polymer matrix these smuld therefore significantly increase its conductivity provided that the CT complexes are ordered, because their high conductivity is related to the strong interactions between donor and acceptor stacks in the crystal. We describe here a new method of introducing microcrystalline CT complexes into polymers. It consists of growing microcrystals during film casting. The system, poly (bisphenol A carbonate)/(PC) with microcrystals of the CT complex of 7,78,8-tetra-cyanoquinodimethane (TCNQ) with tetrathiotetracene (TTT), reaches the dark conductivity of 3 × 10−2Ω−1cm−1at room temperature at 1 wt% of the complex. This conductivity is only slightly temperature dependent.
