在诸如太阳能电池之类的薄膜电子器件的制造中，通常通过旋涂从溶液中沉积分子成分。有毒的氯化溶剂广泛用于此过程中，并且对环境有益。理想情况下，这些替代产品应该便宜，可再生资源衍生并且能够溶解典型的分子电子材料。此外，它们应允许创建薄膜，在其中可以控制不同组件的相互扩散，以优化最终器件的性能。在初步调查中，我们检查了聚（3-己基噻吩）（P3HT）和[6,6]-苯基-C ₆₁层的沉积-丁酸甲酯（PCBM），它们是基准分子半导体，已分别在太阳能电池中广泛用作电子给体和受体。我们已经发现，柠檬烯（柠檬类水果和其他植物产生的绿色溶剂）中的溶液对于在P3HT上沉积PCBM以创建双层体系结构特别有效。如通过TOF-SIMS测量所确定的，当使用柠檬烯代替标准的氯化溶剂时，P3HT底层的润湿性得到改善，并且PCBM和P3HT的相互扩散得以减少。我们的结果强调了非常规绿色溶剂（如柠檬烯）在制造分子薄膜电子设备中的潜力。

Limonene as a Green Solvent for Depositing Thin Layers of Molecular Electronic Materials with Controlled Interdiffusion

In the fabrication of thin-film electronic devices such as solar cells, molecular components are often deposited from solution by spin-coating. Toxic chlorinated solvents are widely used in this process, and environmentally benign alternatives are desirable. Ideally, these alternatives should be inexpensive, derived from renewable sources, and able to dissolve typical molecular electronic materials. Moreover, they should allow the creation of thin films in which the interdiffusion of different components can be controlled to optimize the performance of the resulting device. In an initial survey, we have examined the deposition of layers of poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C₆₁-butyric acid methyl ester (PCBM), which are benchmark molecular semiconductors that have been widely used together in solar cells as electron donor and acceptor, respectively. We have found that solutions in limonene (which is a green solvent produced by citrus fruits and other plants) are particularly effective for depositing PCBM on P3HT to create bilayer architectures. Wetting of the P3HT underlayer is improved when limonene is used in place of standard chlorinated solvents, and interdiffusion of PCBM and P3HT is reduced, as established by TOF-SIMS measurements. Our results underscore the potential of unconventional green solvents such as limonene for use in fabricating molecular thin-film electronic devices.
