only that the acid form is observed as coexisting with H-aggregates. The solubility markedly decreased when the chain length increased. The residual ethanol (0.2% v/v) used to facilitate the solubilisation of the benzo[a]phenoxazinium dyes allow for the existence of the basic form in an aqueous solution, possibly through preferential solvation. Photophysical studies in the presence of DNA revealed that
有效地合成了在杂环部分的5位具有丙基,辛基,癸基,十二烷基或十四烷基氨基的几种荧光苯并[ a ]苯恶嗪氯化物。所有化合物的吸收和发射最大值分别在627–638 nm和654–678 nm范围内,并具有良好的荧光量子产率。对它们在乙醇中的光物理性质的研究可以估算酸碱解离常数K a。揭示了随着烷基侧链长度的增加而增强。仅在水性介质中,观察到酸形式与H-聚集体共存。当链长增加时,溶解度显着降低。用于促进苯并[ a ]苯恶嗪鎓染料增溶的残余乙醇(0.2%v / v)可以通过优先溶剂化使碱性形式存在于水溶液中。在存在DNA的情况下进行的光物理研究表明,具有最多8个碳原子的烷基侧链的化合物可以插入DNA核苷酸之间。此外,发现其他形式的DNA结合也是有效的,其中还涉及苯并[ a ]苯恶嗪鎓染料的基本形式。

A Nile blue-based chemodosimeter (1) was newly synthesized, and its application for detection of the Hg2+ ion in 100% aqueous solution was demonstrated. Upon its addition into aqueous Hg2+ ion solution, it exhibited a considerable blue-shift in its absorption and emission spectra, driven by a desulfurization reaction. Detection at an emission of 652 nm was extremely sensitive (less than 1.0 ppb), even in biological media such as blood plasma and albumin.
