STM study of the self-assembly at the solid–liquid interface of substituted guanines exposing in the N9-position alkyl side chains with different lengths revealed the formation of distinct crystalline nanopatterns.

naphthyridine–aniline conjugated molecules are selective sensors of decylguanine in dichloromethane and guanosine monophosphate in water (Kass = 16 000 M–1). The 2-acetamido-1,8-naphthyridine moiety binds with guanine in a DAA–ADD triply hydrogen-bonded motif. The aniline moiety enhances an electron-donating effect, and the substituent is tuned to attain extra hydrogen bonds, π–π stacking, and electrostatic interactions
乙炔连接的萘啶-苯胺共轭分子是二氯甲烷中癸基鸟嘌呤和水中鸟苷单磷酸(K ass = 16 000 M –1)的选择性传感器。2-乙酰氨基-1,8-萘啶部分与鸟嘌呤结合在DAA-ADD中,为氢键结合的三重基序。苯胺部分增强了给电子作用,对取代基进行了调节以获得额外的氢键,π-π堆积和静电相互作用。提出的结合模式得到Job图,ESI-MS,1 H NMR,UV-vis和荧光光谱分析的支持。

membranes. We report the synthesis of five new guanine–N9 derivatives bearing alkyl chains with different attachment chemistries, exploiting a synthesis pathway that allows a flexible choice of hydrophobic anchor moiety. In this study, these guanine derivatives were functionalized with C10 chains for insertion into decanoic acid bilayer structures, in which both alkyl chain length and attachment chemistry
