摘要
本文叙述了两个同质查耳酮系列的合成.一个带有查耳酮中心链(系列Ⅰ),另一个是系列Ⅰ的酯类(系列Ⅱ).研究了每个系列中三种化合物的发光,发现两个系列的所有化合物都能见到发光.系列Ⅰ中的化合物在峰值为360nm处可见到发光,而系Ⅱ列中的化合物未能观测到这一波长的发光.然而,在峰值为470nm处两者均可见到发光.得出的结论是,消除非键电子微扰作用的氢键是系列Ⅰ中的化合物在360nm处出现发光的原因.
Two homologous series, ono with a chalcone central linkage (Series 111111111) and other the esters of the series 11111111 (Series 222222222 ) have been synthesised. Three compounds from each series have been inyestigatcd for their luminescent behaviour. All the members of both series show fluorescence. It is observed that the 360 nm emission which is present in series I compounds is absent in the emission spactra for series I compounds. However, another emission at 470 nm is observed in compounds of both series. It has bean concluded that hydrogen bond which removes the perturbing effect of the non-bonding electron is responsible for the presence of 360 nm emission in the compounds of Series 1111111111 .
