The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 1-Bromoundecane(SMILESS: CCCCCCCCCCCBr,cas:693-67-4) is researched.Reference of 2,6-Dimethyl-3,5-heptanedione. The article 《Alkyl Chain Tuning of Small Molecule Acceptors for Efficient Organic Solar Cells》 in relation to this compound, is published in Joule. Let’s take a look at the latest research on this compound (cas:693-67-4).
The field of organic solar cells has seen rapid developments after the report of a high-efficiency (15.7%) small mol. acceptor (SMA) named Y6. In this paper, we design and synthesize a family of SMAs with an aromatic backbone identical to that of Y6 but with different alkyl chains to investigate the influence of alkyl chains on the properties and performance of the SMAs. First, we show that it is beneficial to use branched alkyl chains on the nitrogen atoms of the pyrrole motif of the Y6. In addition, the branching position of the alkyl chains also has a major influence on material and device properties. The SMA with 3rd-position branched alkyl chains (named N3) exhibits optimal solubility and electronic and morphol. properties, thus yielding the best performance. Further device optimization using a ternary strategy allows us to achieve a high efficiency of 16.74% (and a certified efficiency of 16.42%).
