以结构规整、密度低、热稳定性* 的共价有机多孔骨架(COF-SDU1)为基质,根据配位化学原理,将稀土β-二酮类铕配合物Eu(TTA)_3-Phen引入到该多孔基质中,得到稀土杂化材料(Eu(TTA)_3Phen-@COF-SDU1)。对合成材料的结构进行傅里叶变换红外光谱(FT-IR),紫外-可见光谱(UV-Vis)和N2吸附-脱附(BET)分析,结果表...
The GS-SSF were prepared using a two-step electrochemical etching method, and the covalent organic framework (COF) TFPA-TTA-COF coating was chemically bonded to the gully-like surface via in situ growth. The prepared metal fibers were applied as the headspace solid-phase microextraction (HS- ...
In this paper, a novel robust TFPA–TTA–COF coating with nano pores was grafted to the gully-like surface of stainless steel fibers (GS-SSF). The GS-SSF were prepared using a two-step electrochemical etching method, and the covalent organic framework (COF) TFPA–TTA–COF coating was ...
