我们提出了一种利用有机掺杂实现有机基质稳定n型掺杂的方法。为了克服强有机供体固有的稳定性限制，我们在原位从稳定的前体化合物中产生供体。作为一个例子，研究了氯化派罗宁B作为掺杂剂在1，4，5，8-萘四酸二酸酐基质中的应用。获得了高达2×10−4 S/cm的电导，比以前用双(乙二硫基)四硫富瓦烯作为掺杂剂得到的电导高出两个数量级[A.Nollau，M.Pfeiffer，T.Fritz，K.Leo，J.Appl.太棒了。87,4340(2000)]。场效应测量被用来证明n型导电。其他可以掺杂的基质是N，N‘-二甲基茂-3，4，9，10-四羧酸二亚胺和富勒烯C60，它们经常用于有机太阳能电池。可见光和傅里叶变换红外光谱证实了派罗宁B的给体性质。
We present an approach to stable n-type doping of organic matrices using organic dopands. To circumvent stability limitations inherent in strong organic donors, we produce the donor from a stable precursor compound in situ. As an example, pyronin B chloride is studied as a dopant in a 1,4,5,8-naphthalene tetracarboxylic dianhydride matrix. Conductivities up to 2×10−4 S/cm are obtained, which is two orders of magnitude higher than obtained previously using bis(ethylenedithio)-tetrathiafulvalene as a dopant [A. Nollau, M. Pfeiffer, T. Fritz, and K. Leo, J. Appl. Phys. 87, 4340 (2000)]. Field-effect measurements are used to prove n-type conduction. Other matrices which can be doped are N,N′-dimethyl-perylene-3,4,9,10-tetracarboxylic diimide and fullerene C60, frequently used in organic solar cells. Visible light and Fourier-transform infrared spectroscopy confirm the donor properties of pyronin B.
