endowed with reactive ethynylgroups on the walls of one-dimensional pores, has been used as a platform for pore-wall surface engineering with triazole and thiol groups to yield TPB-DMTP-COF-SH, which is suitable to interact very efficiently with mercury ions. The evaluation of the carefully designed TPB-DMTP-COF-SH is addressed as an effective and selective system for mercury sorption. The obtained
亚胺连接的共价有机骨架([HC≡C]0.5-TPB-DMTP-COF),在一维孔壁上具有反应性乙炔基,已用作三唑和硫醇基进行孔壁表面工程化的平台,从而生成TPB-DMTP-COF-SH,适合与汞离子非常有效地相互作用。精心设计的TPB-DMTP-COF-SH的评估被认为是有效且选择性的汞吸附系统。所得结果表明,具有非常高的分布系数值K d = 3.23×10 9的聚合物材料具有非凡的容量和极高的效率。因此,高浓度水溶液中的汞含量为10 mg L -1用TPB-DMTP-COF-SH处理几分钟后,汞(II)的含量显着降低,低于被认为是饮用水的极限。水中Hg(II)的TPB-DMTP-COF-SH保留值在2分钟内为99.98%,其记录的吸收容量为4,395 mg g -1,这是迄今为止报道的最高值。除了TPB-DMTP-COF-SH,它还捕获其他毒性极高的重金属离子,例如Sn(II)和Pb(I

purely organic donor–acceptor materials with integrated π‐bowls (πBs) that combine not only crystallinity and high surface areas but also exhibit tunable electronic properties, resulting in a four‐orders‐of‐magnitude conductivity enhancement in comparison with the parent framework. In addition to the first report of alkyne–azide cycloaddition utilized for corannulene immobilization in the solid state
