Polydisperse edge-fused nickel(II) porphyrin nanoribbons have been synthesized by Yamamoto coupling followed by gold(III)-mediated fusion, with average degrees of polymerization of up to 37 repeat units (length 31 nm). Time-resolved optical-pump terahertz spectroscopy measurements indicate that photo-generated charge carriers have dc mobilities of up to 205 cm V s in these nanoribbons, exceeding the values previously reported for most other types of nanoribbon or π-conjugated polymer.
通过山本偶联反应，随后进行金（III）介导的融合，合成了多分散的边缘融合镍（II）卟啉纳米带，其平均聚合度高达37个重复单元（长度为31纳米）。时间分辨光泵太赫兹光谱测量表明，在这些纳米带中，光生电荷载流子的直流迁移率高达205厘米²伏⁻¹秒⁻¹，超过了之前报道的大多数其他类型纳米带或π共轭聚合物的值。
