  摘要：

  有机−无机杂化溶胶−凝胶基质被用作三氟乙酰-p-十烷苯（TFADB）的宿主，TFADB是一种传统的碳酸离子载体。该溶胶−凝胶前驱体是通过（3-异氰丙基）三乙氧基硅烷与乙二醇的反应制备的。十六烷基三甲氧基硅烷（HDTMOS）被用作共前驱体。适量的三十二烷基甲基氯化铵（TDMAC）和2-硝基苯基辛基醚（NPOE）被用作膜成分。与酸性催化剂混合后，溶胶态前驱体缓慢凝胶化，形成了一种膜，活性成分TFADB和TDMAC被封装其中。采用红外光谱、1H 和 29Si MAS NMR仪器来监测溶胶−凝胶过程和聚合程度。基于溶胶−凝胶膜的电极性能与基于TFADB的聚氯乙烯（PVC）膜电极进行了比较。TFADB:TDMAC（1:0.14）摩尔比的膜显示出延长的使用寿命和稳定的基线电位。在18°C时，针对碳酸盐的响应斜率约为27 mV/十倍浓度范围，浓度范围为10^-5至10^-3.5 M。有趣的是，对碳酸盐的选择性相对于水杨酸盐和其他脂溶性阴离子得到了改善，明显偏离了霍夫迈斯特选择性模式。针对氯离子和硫酸根等小无机阴离子的响应可以忽略不计。在0.1 M三硫酸盐缓冲液（pH 8.75）中，通过匹配电位法测得的选择性系数为log K = -0.3，log K = -4.2，和log K = -2.5。

  Organic−inorganic hybrid sol−gel matrixes were used as hosts for trifluoroacetyl-p-decylbenzene (TFADB), a traditional ionophore for carbonate. The sol−gel precursor was prepared by the reaction of (3-isocyanopropyl)triethoxysilane with ethylene glycol. Hexadecyltrimethoxysilane (HDTMOS) was employed as a co-precursor. An appropriate amount of tridodecylmethylammonium chloride (TDMAC) and 2-nitrophenyloctyl ether (NPOE) were used as membrane components. On mixing with an acidic catalyst, the sol-state precursors slowly gelled, yielding a membrane in which the active components, TFADB and TDMAC, were encapsulated. Infrared, 1H, and 29Si MAS NMR spectrometers were employed to monitor the sol−gel process and the degree of polymerization. The performances of the sol−gel membrane-based electrodes were compared to those of TFADB-based poly(vinyl chloride) (PVC) membrane electrodes. Membranes with a molar ratio of TFADB:TDMAC (1:0.14) showed extended lifetime and stable baseline potential. The response slope toward carbonate was approximately 27 mV/decade between 10-5 and 10-3.5 M at 18 °C. Interestingly, selectivity toward carbonate over salicylate and other lipophilic anions was improved, clearly deviating from the Hofmeister selectivity pattern. Responses toward small inorganic anions including chloride and sulfate were negligible. The selectivity coefficients measured by the matched potential method in 0.1 M tris-sulfuric acid buffer, pH 8.75, were log = −0.3, log = −4.2, and log = −2.5.

  Through the reaction between the hydroxyl groups of 2-hydroxyl-3-methylbenzoic acid (HMBA), the glycol (G), the diglycol (DG) or the polyethylene glycol (PEG) and the isocyanate groups of 3-(triethoxysilyl)-propyl isocyanate (TEPIC), the hybrid precursors HMBA-Si, G-Si, DG-Si and PEG-Si were obtained. And then the precursors HMBA-Si and G-Si (DG-Si, PEG-Si) have coordinated to the rare earth ions with the carbonyl group of G-Si (DG-Si, PEG-Si) and the carboxyl group of HMBA-Si to form the hybrid materials HMBA-G-RE-Si (HMBA-DG-RE-Si, HMBA-PEG-RE-Si) through hydrolysis and copolycondensation with the tetraethoxysilane (TEOS) via sol-gel process. Subsequently, the NMR, FT-IR and ultraviolet absorption spectra have indicated that the effective precursors have been obtained successfully and the obtained materials possess the characteristic. fluorescent properties, thermal stabilities and regular trunk with hole-like microstructures.
