第二章,我们用稳态荧光光谱法研究了双头基两亲型化合物对长链烷基β--萘甲酸酯的解簇集作用;结果发现,解簇集作用不仅依赖于簇集体的起始浓度而且还依赖于溶剂的促簇能力。

However, any substitution on the naphthyl ring decreased the bioactivity.

但若萘环上有取代基,将大大降低其生物活性。

Some products included methoxy group, naphthyl and heterocyclic aromatic moieties, and some were borne with two 1-propynyl groups. It is more important that compounds bearing halogens were also synthesized via this protocol.

The microwave-assisted reactions could be finished within several minutes to give high conversion and selectivity.Substrates whose aryl groups were substituted phenyl or naphthyl groups were more suitable in this reaction.

以TfOH为催化剂,在优化的反应条件下,大部分反应都可在数分钟内完成,该反应对于芳基是取代苯环或萘环的的底物效果较好,能得到较高的原料转化率和产物选择性。

Absorption spectra indicate that there is little or no interaction between chromphores in the ground state. However, the fluorescence emission of oxadiazole and triphenylamine moieties are almost quenched, which shows that in the excited ground state there exists very effective intramolecular singlet-singlet energy transfer .

研究发现,这些多发色团化合物在基态发色团之间没有作用或作用很小,而其中噁二唑和三苯基胺单元的荧光被严重的猝灭,这说明在激发态下,萘酰亚胺发色团与噁二唑、三苯胺功能团之间发生了分子内单线态—单线态能量转移。
