尤其是SCI論文正文中最開始的Introduction更是讓廣大小伙伴犯難?今天博遠教育就和大家分享一下如何從頂刊來學習introduction應該怎么寫。

introduction怎么寫

寫作Introduction之前,我們首先需要了解好的Introduction應該有哪些關鍵部分:

①下一個引人注目的“鉤子”,便于吸引審稿人和讀者的注意;

②重要的背景信息,顯示自己的研究在本領域的重要性;

③一個可證明和具體的陳述,自己論文研究的具體問題,或如何解決改善了某些事情。

我們來看Nature Chemistry中的一個例子,它的標題是Long-range ordered and atomic-scale control of graphene hybridization by photocycloaddition (Nat. Chem. 12, 1035–1041 (2020). https://doi.org/10.1038/s41557-020-0540-2)

Nature Chemistry

圖源:Nat. Chem. 12, 1035–1041 (2020)

從這篇文章的題目和它的TOC我們就能知道它的研究內容是:石墨烯+可控+ photocycloaddition。讓我們思考一下,如果是我們自己寫這個研究內容的論文,我們該如何來寫Introduction?

首先一定和石墨烯相關,其次是石墨烯的官能化可控性的重要性,photocycloaddition的意義(為什么選擇這個反應而不是其他的)。

我們來看作者是如何進行第一步“下鉤子”的:

Since its isolation as a two-dimensional (2D) system, graphene has been widely acclaimed due to its extraordinary physical and chemical properties, showing great promise for next-generation electronic and optoelectronic devices1,2,3. However, graphene’s zero bandgap limits its use as an active layer in electronic devices. To pave the way towards practical applications, the functionalization of graphene has been a topic of much interest4. A broad variety of functionalization approaches have been developed, such as ... Controllable and precise functionalization of graphene remains a major challenge, despite considerable progress.

作者首先在第一句話引出所研究的材料石墨烯,借著用一個當前存在的問題(However, graphene’s zero bandgap limits)當鉤子,引出the functionalization of graphene和XXX remains a major challenge, despite considerable progress的重要性和意義。

鉤子一般的使用方法就是先闡明一個東西是多么的有應用前景,多么的優秀,然后再提出當前所存在的問題,而這個問題恰恰就是自己文章所解決的問題(這個非常重要,否則你寫的introduction和你的論文可能一點關系都沒有,直接會被拒掉的哦)。

接下來作者開始介紹重要背景:

Cycloaddition has been demonstrated to be an effective path for introducing sp3 hybridization and thereby functionalizing graphene26,27,28. … Even if the reactions were induced, they occur randomly4 or strongly depend on the graphene Moiré pattern formed on specific substrates30,31, and it is difficult to exclude the disturbance from solvent and impurities for the reactions occurred in solution. So far it has not been possible to realize chemical reactions of graphene with molecular networks or to achieve 2D order of reaction sites with atomic/molecular precision. Superior to the reactions that require long soaking, heating, electric pulse or probe tip press, the merits of photocycloaddition—such as simplicity, remote controllability and compatibility with other photorelated techniques—have been recognized; nevertheless, photocycloaddition of graphene has been scarcely reported, with only precedent in aqueous solution32.

重要背景包括Cycloaddition(因為作者研究的photocycloaddition就是環加成的一種)的現狀,然后是存在的問題they occur randomly4 or strongly depend on…。接著作者總結了這個研究領域的結果So far it has not been possible to…。最后作者再次引領讀者關注自己的研究內容photocycloaddition的現狀, photocycloaddition of graphene has been scarcely reported。

最后闡述自己論文研究的具體問題:

Here we report an in situ photocycloaddition reaction of an extended molecular network placed on a single-layer defect-free pristine graphene sheet in ultrahigh vacuum (UHV), … and confirmed by ab initio density functional theory (DFT) calculations. … The reaction is triggered by ultraviolet irradiation at room temperature, with the reaction sites being spatially selective and arranged in 2D long-range order.

Here we report是introduction常用的開頭,接著突出自己的重要研究方法,比如這里是實驗+計算(density functional theory (DFT) calculations)。最后表明自己的重要結果/結論spatially selective and arranged in 2D long-range order,與前兩部分所提出的問題完美契合。

這樣一篇出色的introduction就完成了,分成三步,按部就班。記得鉤子要吸引人,背景要詳實卻不贅述,結論/結果的陳述對應自己所提出的現狀問題哦。
