隨著化石資源的日益枯竭以及人們環(huán)保意識的增強(qiáng),基于可再生資源的高分子材料越來越受到人們的重視。木質(zhì)纖維素是地球上儲量最豐富、分布最廣泛的生物質(zhì)資源,通過化學(xué)或生物轉(zhuǎn)化的方法可獲得豐富多樣的的生物基平臺化學(xué)品,其中部分已成功用于生物基合成高分子。如香草醛作為一種典型的木質(zhì)素轉(zhuǎn)化的芳香化合物,已經(jīng)實(shí)現(xiàn)工業(yè)化的生產(chǎn),基于香草醛開發(fā)新型的生物基高分子備受關(guān)注。但是如何高效、綠色將香草醛轉(zhuǎn)化為可聚合單體,實(shí)現(xiàn)其高效、可控聚合是挑戰(zhàn)。
近期,貴州大學(xué)材料與冶金學(xué)院高分子材料與工程系謝海波教授課題組在國際綠色化學(xué)權(quán)威期刊《Green Chemistry》(一區(qū),IF=9.4)發(fā)表了題為“Introducing the Tishchenko Reaction into Sustainable Polymer Chemistry”的研究論文,第一作者為我院2017級碩士研究生仁天華,指導(dǎo)老師謝海波教授、陳沁副教授,并被主編推薦為后封面論文。文章工作歷時(shí)四年時(shí)間,首次報(bào)道了將季先科反應(yīng)成功應(yīng)用于可聚合單體的合成,制備了新型含有羧酸酯官能團(tuán)的二烯烴單體,再利用溫和的巰烯點(diǎn)擊聚合和非環(huán)二烯易位聚合方法,可控合成高分子量的的系列新型生物基聚酯,并對聚酯做了后改性研究。本研究提供了聚酯合成的新思路、新策略,為生物質(zhì)高效利用,生物基合成高分子新材料的分子設(shè)計(jì)、可控制備及應(yīng)用,提供了重要的理論依據(jù)和技術(shù)參考。
審稿人一致認(rèn)為論文具有非常重要的科學(xué)價(jià)值和應(yīng)用前景。“This is a strong paper with the potential to lead to significant further research and subsequent industrial use of bio-based starting materials in the preparation of significantly more sustainable polymers than their petrochemical-based alternatives. Aside from a few minor grammatical errors which should be corrected before publication, I recommended acceptance by Green Chemistry”,“The manuscript presents the preparation of α,ω-diene functionalized carboxylic ester monomers by combined Williamson and Tishchenko reactions using renewable starting materials. It also demonstrates the preparation of poly(thioether esters) and unsaturated polyesters from the monomers. The scientific merit of the paper is very high. I highly recommend it to be published without any correction”。
