點(diǎn)擊化學(xué)Click chemistry是2001年美國諾貝爾化學(xué)獎(jiǎng)獲得者K. Barry Sharpless等提出的一系列反應(yīng),其核心是開辟一整套以含雜原子鏈接單元C—X—C為基礎(chǔ)的組合化學(xué)新方法,用少量簡單可靠和高選擇性的化學(xué)轉(zhuǎn)變來獲得更廣泛的分子多樣性。雖然應(yīng)用時(shí)間不長,但是點(diǎn)擊化學(xué)已經(jīng)成為材料科學(xué)中最經(jīng)典的范例性反應(yīng)之一。由于“點(diǎn)擊反應(yīng)”具有的高 效和高控制性,在化學(xué)合成領(lǐng)域掀起了一場風(fēng)暴。所謂可靠的化學(xué)反應(yīng)意指這些反應(yīng)能夠產(chǎn)生高立體選擇性的產(chǎn)物,且其副產(chǎn)物無毒而對氧氣和水不敏感,這意味著產(chǎn)物具有相當(dāng)高的穩(wěn)定性。此專題文章系統(tǒng) 全面的介紹了其在材料科學(xué)中的應(yīng)用。 Click Chemistry in Materials Science Weixian Xi, Timothy F.

Kloxin Department of Chemical & Biomolecular Engineering University of Delaware 150 Academy Street , Newark, Delaware 19716 , USA The marriage between click chemistry and materials science is one that had been destined to occur for many years. Perhaps more than in any other field, the goal of materials scientists, engineers, and manufacturers has been to achieve performance and a set of desired characteristics in the final material and/or device in as simple and effective a manner as possible. These performance targets include specifi cations on mechanical and physical behavior, such as toughness, modulus, glass transition temperature, refractive index, and clarity, as well as chemical attributes such as solvent (in)compatibility, surface energy, chemical functionality, and biocompatibility. Process considerations such as the raw materials, process safety, solvent, and environmental considerations are also of great importance. This focus on material properties and performance aligns well with the goals espoused by Sharpless and coworkers when they fi rst introduced the “click” chemistry paradigm, wherein they argued that the focus of chemical process selection should be directed towards the identifi cation, optimization, and simplification of an overall process.Thus, this process identification includes the selection of initial target molecules, starting materials, and the reactions used to synthesize them, ultimately leading to the straightforward generation of a compound with the desired properties via a simple, robust process. |
