Rational Extension of the Family of Layered, Covalent, Triazine‐Based Frameworks with Regular Porosity

Carbonization of covalent triazine-based frameworks via ionic liquid induction

“…The conclusion obtained from solid-state NMR was also supported by IR and EA. The presence of an extra-peak in both NMR spectra of KPOP-6a and KPOP-6b, located at 173.4 ppm attributed to the characteristic peak of triazine, 18,40 confirmed the presence of triazine moieties. Based on the EA, IR and solid-state NMR analysis, it was evident that ionic liquid catalyst of molten ZnCl 2 promoted the carbonization of the POPs' frameworks leading to extended pore apertures.…”

“…Porous organic polymers (POPs), an inorganic node free version of porous materials (including crystalline covalent organic frameworks (COFs), 6 and amorphous porous aromatic frameworks (PAFs), 7 polymers of intrinsic microporosity (PIMs), 8 porous polymer networks (PPNs), 9 covalent triazinebased frameworks (CTFs) [10][11][12][13][14][15][16][17][18][19] ) are attracting more and more attention because of their great potential for practical applications, for example, gas storage, separation, catalysis, and electronic device. 20 Among these materials, CTFs can be obtained by using a cheap catalyst such as ZnCl 2 and possess high chemical and thermal stability.…”

“…According to the literatures, there are only a few reports on crystalline CTFs, and all of them display twodimensional structures with π-π stacking interactions between the adjacent layers. 17,18,34 TGA (Fig. S2) was carried out under O 2 atmosphere to study POPs' thermal stability.…”

Dirac Cones in two-dimensional conjugated polymer networks

“…1b using a trivalent 1,3,5-triazine connecting group. 2D COFs can now be synthesized using dynamic covalent chemistry in milligram quantities 9 organic monomers, with solvothermal 10 , microwave 11,12 and ionothermal 13,14 synthesis in solution or directly as monolayers on metallic 15 and graphitic 16,17 substrates. Solution-based monoand few-layer sheets can now be produced at micron diameters, highly crystalline 18 and largely defect-free 19 .…”

Designed Synthesis and Characterization of Novel Germanium Centered Porous Aromatic Frameworks (Ge-PAFs)

“…随着大量科研 工作者的不断努力, 许多有机反应被不断尝试并且成功 的制备了大量的多孔有机聚合物, 例如: 硼酸聚合 [7～10] , 镍 催 化 的 Ullmann 偶 联 反 应 [11 ～ 16] , 钯 催 化 的 Sonogashira-Hagihara 偶联反应 [17,18] , 钯催化的 Suzuki 偶 联 反 应 [19 ～ 20] , 氰 基 自聚 反 应 [21,22] . 其 中 钯 催 化的 Suzuki 偶联反应作为一种反应条件容易控制, 原料价格 便宜并且具有极高产率的优秀反应为众多化学家所广 泛关注及使用 [23,24] .…”
