多枝状季铵盐类化合物及其制备和用途
摘要：
本发明涉及一种多枝状季铵盐类化合物及其制备和用途。所述的多枝状季铵盐类化合物具有式Ⅰ所示结构。本发明所述的多枝状季铵盐类化合物可作为以酸性硫酸铜为电镀液电镀铜的整平剂的应用。式I中，R1为C1～C15直链或支链烷基或C4～C12直链或支链全氟烷基，R2为C1～C8直链或支链烷基，X为Cl、Br或I，M为H、Na或K，n为2～8的整数。
摘要（英）：

The invention relates to a multi-dendritic quaternary ammonium compound, and preparation and use thereof. The multi-dendritic quaternary ammonium compound has a structure as shown in a formula I. The multi-dendritic quaternary ammonium compound provided by the invention can be applied as a leveling agent for electrocoppering with acidic copper sulfate as an electroplating liquid. In the formula I, R1 is a C1-C15 linear or branched alkyl or a C4-C12 linear or branched perfluoroalkyl group; R2 is C1-C8 linear or branched alkyl; X is Cl, Br or I; M is H, Na or K; n is an integer ranging from 2 to 8.
