ethylenediamine spacer using a succinct synthetic route to give a bromoacridine-linked, bifunctional fluorophore conjugate for the detection of triplex DNA. Acridine is well known to intercalate into duplex DNA whereas introduction of a bulky bromine atom at position C2 redirects specificity for triplex over duplex DNA. In this work, photoelectron transfer assay was used to demonstrate that the synthesised
使用简洁的合成路线,荧光团 1,8-萘甲酰胺通过乙二胺间隔基与 2-溴吖啶连接,得到溴吖啶连接的双功能荧光团偶联物,用于检测三链 DNA。众所周知,吖啶嵌入双链 DNA 中,而在 C2 位置引入庞大的溴原子会重定向双链 DNA 对三链的特异性。在这项工作中,光电子转移试验用于证明合成的 2-溴吖啶连接的荧光团缀合物对代表性的三链 DNA 靶序列 d(T*AT) 20与双链 d(TA) 20相比具有良好的选择性,单链-链 dT 20或 d(G/A) 19 DNA 序列。 图形摘要
Unexpected fluorescent behavior of a 4-amino-1,8-naphthalimide derived β-cyclodextrin: conformation analysis and sensing properties
A new fluorescent cyclodextrin shows unexpected and strong fluorescence enhancement upon binding of organic molecules, and the enhancing mechanism is found to be different from those reported in the literature.

AbstractEfficient synthesis of fluorescent probes based on 1,8-naphthalicanhydride from acenaphthene with the help of microwave irradiation is described. Application of microwave dielectric heating helped improve the yield of the products (>85%) and also reduced the formation of undesired side-products. Graphical Abstract
