A first hexaphenylsilole-based conjugated microporous polymer, termed THPS, was prepared by a Friedel-Crafts arylation reaction of 1,1,2,3,4,5-hexabenylthirole with 2,4,6-trichloro-1,3,5-triazine catalyzed by anhydrous aluminium trichloride (AlCl) in 1,2-dichloroethane. Its Brunauer-Emmett-Teller and Langmuir surface area reached up to 1579 and 2081 m g, and total pore volume and micropore pore volume were severally 0.8325 and 0.7322 cm g. THPS could fluorescence-sense o-nitrophenol with high sensitivity and selectivity. Its fluorescence quenching constant (K) and limits of detection (LODs) were severally 8.32 × 10 L mol and 3.61 × 10 mol L. The fluorescence quenching of THPS by o-nitrophenol was originated from the combined action of both photo-induced electron transfer mechanism and resonance energy transfer mechanism.
一种基于六苯基硅芴的共轭微孔聚合物，称为THPS，通过在1,2 - 二氯乙烷中，以无水三氯化铝（AlCl）为催化剂，使1,1,2,3,4,5 - 六苄基噻咯与2,4,6 - 三氯 - 1,3,5 - 三嗪发生傅克芳基化反应制备而成。其布鲁诺尔 - 埃米特 - 泰勒比表面积和朗缪尔比表面积分别达到1579和2081 m²/g，总孔体积和微孔孔体积分别为0.8325和0.7322 cm³/g。THPS能够对邻硝基苯酚进行高灵敏度和高选择性的荧光传感。其荧光猝灭常数（K）和检测限（LOD）分别为8.32×10⁴ L/mol和3.61×10⁻⁷ mol/L。邻硝基苯酚对THPS的荧光猝灭源于光诱导电子转移机制和共振能量转移机制的共同作用。
