incorporates a well-known efficient fluorophore, i.e.: 1,8-diaminonaphthalene. The high fluorescence quantum yield shared by most naphthalene derivatives, has enabled their use as stains for bio-imaging and biophysical characterizations. However, fluorescence is dramatically depressed in perimidine as well as in the few of its derivatives analysed so far to this respect. The use of perimidine-like molecules in
Perimidines是一个特别通用的杂环化合物家族,其性质在从工业化学到药物化学的多种应用中得到了利用。Perimidine的分子结构结合了众所周知的有效荧光团,即:1,8-二氨基萘。大多数萘衍生物具有很高的荧光量子产率,从而使其可用作生物成像和生物物理表征的染色剂。但是,到目前为止,在此过程中,perimidine及其少数衍生物的荧光显着降低。通过增强其荧光发射,可以显着促进在生命科学中使用类似过二甲酰亚胺的分子。更令人兴奋的是 具有相同分子结构的生物活性部分和荧光团的并存实际上揭示了在医学上最先进的治疗方法规程中perimidines作为药物的应用。然而,出乎意料的是,迄今为止,在提高perimidines作为荧光染料的性能的方向上进行了相对较少的尝试。在这项工作中,我们介绍了为此目的设计的四种perimidine衍生物的合成和光谱表征,其中两种结果具有与1,8-二氨基萘相当的荧光量
