A novel triazene-anthracene-based fluorescent aminal linked porous organic polymer (TALPOP) was prepared via metal free-Schiff base polycondensation reaction of 9,10-bis-(4,6-diamino-S-triazin-2-yl)anthracene and 2-furaldehyde. The polymer has exceptional chemical and thermal stabilities and exhibit good porosity with Brunauer-Emmett-Teller surface area of 401 mg. The combination of such porosity along with the highly conjugated heteroatom-rich framework enabled the polymer to exhibit exceptional iodine vapor uptake of up to 314 wt % and reversible iodine adsorption in solution. Because of the inclusion of the anthracene moieties, the TALPOP exhibited excellent detection sensitivity towards iodine via florescence quenching with K value of 2.9 × 10 L mol. The cost effective TALPOP along with its high uptake and sensing of iodine, make it an ideal material for environmental remediation.
通过9,10-双-(4,6-二氨基-S-三嗪-2-基)蒽与2-糠醛的无金属席夫碱缩聚反应制备了一种新型的基于三氮烯-蒽的荧光胺连接多孔有机聚合物（TALPOP）。该聚合物具有优异的化学和热稳定性，表现出良好的孔隙率，布鲁诺尔-埃米特-泰勒表面积为401平方米。这种孔隙率与高度共轭的富含杂原子的骨架相结合，使该聚合物表现出高达314 wt%的优异碘蒸气吸附量以及在溶液中的可逆碘吸附。由于含有蒽部分，TALPOP通过荧光猝灭对碘表现出优异的检测灵敏度，K值为2.9×10 L/mol。成本效益高的TALPOP及其对碘的高吸附和传感性能，使其成为环境修复的理想材料。
