摘要：A novel triphenylamine-functionalized silsesquioxane monomer (OTS) is synthesized by Heck coupling reaction involving octavinylsilsesquioxane (OVS) and (4-bromophenyl)diphenylamine as the substrates. Subsequently, OTS is used as the precursor to prepare a multifunctional hybrid porous polymer (HLPP-OTS) via Scholl coupling reaction in the presence of AlCl3. HLPP-OTS possesses high surface area of 814 m(2) g(-1) and hierarchical microporous/mesoporous structure. The polymer shows CO2 adsorption capacity of 8.04 wt% (1.83 mmol g(-1)) at 273.0 K/101 kPa as well as high I-2 uptake of 406 wt% in vapor and 468 mg g(-1) in solution. The polymer also exhibits excellent luminescence property and acts as a sensitive chemo-sensor to detect explosives with high sensitivity towards 5-Nitrosalicylaldehyde (K-SV = 36560 M-1).
