2、析、紅外光譜、紫外光譜、熒光光譜表征。結(jié)構(gòu)分析表明,該配合物中,鋅離子處于四配位的四面體構(gòu)型中.分別與2個IAA陰離子的羧基氧原子及1個鄰菲噦啉的2個氮原子配位通過超分子作用力:氫鍵和面對面式的7r?7r堆積作用力的自組裝作用使這些分子形成二維的超分子層結(jié)構(gòu).繼而這些層層間通過邊對面式的7r?7r堆積作用力進一步的組裝成三維的超分子結(jié)構(gòu)。熱重分析顯示,該配合物具有較高的熱穩(wěn)定性。配合物的液態(tài)及固體熒光性質(zhì)研究表明.此配合物具有一定熒光性質(zhì)。關(guān)鍵詞:鋅配合物:晶體結(jié)構(gòu),熒光性質(zhì)中圖分類號:O614.2
