Abstract A new heterojunction film which own MoS2 as the sub-layer and porphyrin (meso-[5-[4(4-methyloxycarbonyl)phenyl][10,15,20-tri[4–tert–butylphenyl]]porphyrin, Por) as the top-lay has been fabricated and characterized. After fabricating into heterojunction film, the morphology and aggregation have been improved due to the effect of heterojunction structure. Furthermore, the devices based on the porphyrin/MoS2 heterojunction films show good sensitivity and selectivity in the detection towards dopamine.

用于超灵敏多巴胺检测的卟啉/二硫化钼薄膜

摘要 一种新型异质结薄膜，以二硫化钼作为亚层和卟啉（内消旋-[5-[4（4-甲氧羰基）苯基][10,15,20-三[4-叔丁基苯基]]卟啉，Por）因为顶层已经被制造和表征。制成异质结薄膜后，由于异质结结构的作用，形貌和聚集得到改善。此外，基于卟啉/二硫化钼异质结薄膜的器件在检测多巴胺方面表现出良好的灵敏度和选择性。
