properties of some representative benzonaphthyridines (3d, 5b and 21f) in homogeneous organic solvents, dioxane–water binary mixtures and in the microheterogeneous media (sodium dodecyl sulphate (SDS), cetyl trimethylammonium bromide (CTAB) and Triton‐X100 micelles) have been examined. A linear correlation between solvent polarity and fluorescence properties was observed. Further, the interaction of these
通过在碱性催化剂中2-氨基喹啉-3-甲醛1与各种脂环族酮的弗里德兰德缩合反应,开发了一种快速高效合成各种多取代苯并[b] [1,8]萘啶的方法(氢氧化钾水溶液)。制备了一系列支链有各种侧链和取代基的苯并[b] [1,8]萘啶,以作为荧光剂进行研究。一些代表性的苯并萘啶(3d,5b和21f)在均相有机溶剂,二恶烷-水二元混合物和微非均相介质(十二烷基硫酸钠(SDS),十六烷基三甲基溴化铵(CTAB)和Triton-X100)中的电子吸收和荧光性质胶束)已经过检查。观察到溶剂极性和荧光性质之间的线性相关性。此外,已通过紫外可见吸收和荧光光谱法检查了这些苯并萘啶(3d,5b和21f)与人血清白蛋白(HSA)和牛血清白蛋白(BSA)在磷酸盐缓冲液中的相互作用。3d,5b和21f的荧光强度随HSA和BSA浓度的增加而增加。这些苯并萘啶也可在磷酸盐缓冲液中猝灭BSA的345 nm荧光(λ EX 280

A series of benzo[b][1, 8]naphthyridines has been synthesized by Friedländer condensation of 2-aminoquinoline-3-carbaldehyde 1 (o-aminoaldehyde) with active methylenes in basic medium. The fluorescence spectroscopic properties of some representative compounds has been studied in different organic solvents; moreover interaction with bovine serum albumin (BSA) in phosphate buffer was examined by UV–vis and fluorescence spectroscopy. The effect of electron donor-acceptor substituents on fluorescence properties of benzo[b][1, 8]naphthyridines 13(a-n) has been investigated along with their fluorescent quantum yields.
