摘要

合成了一种氢键酸性小分子神经毒气敏感材料。以二氯硅烷、2—溴甲基萘、活化锌粉、丙烯基苯为起始原料

通过格氏反应、硅氢加成

制备得到二（苯丙基）—二[（2—萘基）甲基]硅烷

然后用六氟异丙醇进行取代

得到二[3

5—双（2—羟基六氟异丙基）苯丙基]—二{（4

8—三[3

5—双（2—羟基六氟异丙基）]—2—萘基）甲基}硅烷（HPNMS）。将HPNMS涂覆在声表面波（SAW）传感器上

研究了其对神经毒剂模拟剂甲基膦酸二甲酯（DMMP）的气敏特性。结果表明:在（30～170）×10-6的气体体积分数范围内

SAW传感器的响应值与DMMP的含量呈线性关系

对于较厚的敏感膜灵敏度可达266 Hz/10-6。且响应迅速

解吸彻底

对甲苯、丙酮等干扰气体也具有良好的选择性。

Abstract

A hydrogen bond acidic small molecule

bis[3

5-bis（2-hydroxyhexafluoroisopropyl）phenpropyl]bis{4

8-tri[3

5-bis（2-hydroxyhexafluoroisopropyl）]-2-naphthylmethyl}silane（HPNMS）

is synthesized as sensitive material for nerve agents detection.Starting from dichlorosilane

2-（Bromomethyl）naphthalene

activated zinc and Allylbenzene

bis[phenpropyl]bis{2-naphthylmethyl}silane is synthesized by Grignard reaction

hydrosilylation reaction and Reformatsky reaction.The intermediate product is functionalized by hexafluoroacetone（HFIP）to produce the target material HPNMS.The sensitive material is evaluated as adsorbent coatings for nerve agent simulant DMMP on a SAW sensor.The result shows that the frequency shifts are linear to DMMP volume fraction in range of（30 ～170）×10-6 with a sensitivity of 266 Hz/10-6 for a thicker film.Fast response

fully desorption and good selectivity against acetone

toluene etc interferences are achieved.
