2、子自組裝并測定其微/納米結(jié)構(gòu)的氣敏傳感性能。研究顯示,兩種化合物在苯肼氛圍中的靈敏度變化不同,PTCDI—C1F氣敏傳感器電阻下降比PTCDI—CNF高出近2個數(shù)量級,其原因是兩者占據(jù)的最低未占分子軌道(LUMO)能級值相差較大。結(jié)果表明:灣位吸電子取代基的不同對花酰亞胺衍生物微/納米結(jié)構(gòu)的氣敏傳感性能影響顯著。關(guān)鍵詞:吸電子基;j芑酰亞胺;傳感性能;苯肼中圖分類號:O625.52文獻(xiàn)標(biāo)志碼:A文章編號:0367—6358(2016)05—0288—05EffectofCore—substitutedwithDrawingGr
