Application

三甲胺（TMA）已被用于制备聚[9,9′-双（6′-N,N,N-三甲基铵）己基）芴-co-alt-4,7-（2,1,3-苯并噻二唑） 二溴化物]（PFBT），一种用于无标记DNA微阵列的水溶性阳离子偶联聚合物。它还可用于制备苄基三甲基氯化铵，然后与乙醇钠反应以形成苄基三甲基乙醇铵。三甲基甲硅烷基化的硝酸钡-金/钛硅酸盐催化剂金表面上的TMA吸附是丙烯被氧和氢环氧化的促进剂。

We describe the synthesis of poly[9,9'-bis(6''-N,N,N-trimethylammonium)hexyl)fluorene-co-alt-4,7-(2,1,3-benzothiadiazole) dibromide] (PFBT), a cationic, water-soluble conjugated polymer used in label-free DNA microarrays. This polymer was designed to have a maximum absorbance of close to 488 nm, which meets the excitation wavelength of most commercial
