摘要
石墨炔(GYs)是一种新型碳同素异形体,由sp和sp2杂化碳原子组成.其中,石墨双炔(GDY)是目前研究和关注度最广泛的材料.其独特的sp杂化、均匀的孔隙和高度共轭的结构带来了优良的电子、光学和力学特性,其被广泛应用于电子器件、储能和转换、催化、气体分离、海水淡化等领域.然而,GDY材料仍然面临着诸多挑战,包括高结晶GDY的合成和快速无损的表征方法.本文就高结晶度GDY的设计、合成和结构表征进行了综述.本文还描述了GDY在各个领域的应用,为高度均匀的单晶GDY材料带来新的机遇.
Abstract
Graphynes(GYs),as a novel carbon allotrope,are composed of sp-and sp2-hybridized carbon atoms.Among them,graphdiyne(GDY)is the most widely studied and has received great attention.Its unique sp-hybridization,uniform pores,and highly conjugated structures,especially GDY with high crystallinity,bring excellent electronic,optic,and me-chanical characteristics,making them extensively used in electronic devices,energy storage and conversion,catalysis,gas separation,seawater desalination,and so on.However,GDY materials still face challenges,including the synthesis of highly crystalline GDY and the rapid and non-destructive characterization methods.In this review,we primarily sum-marize the design,synthesis,and structural characterization of high-crystallinity GDY.Various applications are also de-scribed,which may bring new opportunities for highly uni-form single-crystalline GDY materials.
