Abstract
New heptamethine cyanine dyes with an alkylamino group at the central position were found to exhibit a large Stokes shift (>140 nm) and strong fluorescence. They were suggested to be a new paradigm for excited-state intramolecular charge transfer (ICT). The configuration change of the bridgehead amine accompanying ICT was investigated in different viscosity and pH media.
摘要
发现中心位置带有烷基氨基的新型七甲川花菁染料表现出较大的斯托克斯位移（>140 nm）和强荧光。它们被认为是激发态分子内电荷转移（ICT）的一种新范例。在不同粘度和pH值的介质中研究了伴随ICT的桥头胺的构型变化。
