Three new triazine-based conjugated microporous polymers with nitrogen as cores containing triphenylamine (TPA), 4,4′,4″-tris(N,N-diphenylamino)triphenylamine (TDATA) and 4,4′,4″-tri[phenyl(m-tonyl)amino]triphenylamine moieties (TMDATA) (TTPA, TTDATA and TTMDATA) were constructed via Friedel-Crafts reaction catalysed by methanesulfonic acid. The resulting CMPs possess high BET surface area of over 308, 491 and 456 m² g⁻¹, large pore volumes, good stability, and display efficient and reversible guest uptake of 4.92, 4.72 and 4.49 g g⁻¹ in iodine vapour which are higher than that of the CMPs with benzene as core. Two ways to release the adsorbed iodine were explored: either slow release into ethanol or quickly release upon heating (with a high degree of control). Spectral studies make us known that the strong affinity for I₂ is mainly due to large porosity, a conjugated π-electron aromatic system, CN bonds, and propeller-like twisted structures. Furthermore, luminescent study indicated that TTPA exhibits high sensitivity to electron-deficient I₂ via fluorescence quenching. TTPA shows the largest amount of iodine adsorption and was the first CMP used fluorescence sensing iodine.

三种新型的以氮为核心的三嗪基共轭微孔聚合物，其中含有三苯胺（TPA），4,4'，4''-三（N，N-二苯氨基）三苯胺（TDATA）和4,4'，4''-三[苯基] （米-tonyl）氨基]三苯基胺部分（TMDATA）（TTPA，TTDATA和TTMDATA）经由由甲磺酸催化的Friedel-Crafts反应，构建。所得的CMP具有超过308、491和456 m ²  g ^-1的高BET表面积，大孔体积，良好的稳定性，并显示出4.92、4.72和4.49 g g ^-1的有效且可逆的客体吸收碘蒸气中的碘含量高于以苯为核心的CMP。探索了两种释放吸附的碘的方法：缓慢释放到乙醇中或加热后迅速释放（高度控制）。光谱研究使我们知道对I ₂的强亲和力主要是由于孔隙率大，共轭π电子芳族系统，C N键和螺旋桨状扭曲结构所致。此外，发光研究表明，TTPA通过荧光猝灭对缺电子的I ₂表现出很高的敏感性。TTPA显示出最大的碘吸附量，并且是使用荧光传感碘的第一批CMP。
