富勒烯 (C60)材料的独特化学和物理学不断刺激着应用和基础科学取得进步。富勒烯作为优异的电子受体而闻名,可以通过化学改性来提高其在有机溶剂中的溶解度。此类可溶性富勒烯衍生物属于已知的最好n型有机半导体1。此外,通过将富勒烯与供电子体或光敏大分子通过共价连接而形成的分子异质结显示了其作为固有p / n型半导体的潜力,甚至有希望成为生物光合作用的人造模拟物。2 为帮助客户在有机电子领域实现研究突破,我们很高兴能为您提供一系列高质量的功能化富勒烯产品。

甲烷富勒烯苯基-C61 -丁酸-甲酯([60] PCBM)是一种有效的溶液可加工型n型有机半导体。其可以与p型共轭聚合物混合制成光伏(PV)电池3,4,以及薄膜有机场效应晶体管 (OFETs)5,在光电探测器领域也显现出了一定的潜力。6与优异的p型半导体一样,[60] PCBM可溶于以下有机溶剂:MDMO-PPV,MEH-PPV和P3HT一类(表1)。这简化了杂化PV电池和OFET中混合物制备和溶液处理的工艺。 PCBM表现出的高亲和力是由p型聚合物以及偏置薄膜OFETs中的金属电极所进行的高效光致电子转移所决定的。7据报道,对于[60] PCBM制得的本体异质结PV电池而言,功率转换效率可以高达〜4.4%。8
