New fluorescent tetrazines have been prepared and their electrochemistry and fluorescence efficiency evaluated. The occurrence of fluorescence as well as the wavelength were found to be strongly dependent on the substituents, which have to be electronegative heteroatoms. This has been rationalized through a computational study that showed that the crucial factor is the nature of the HOMO, which determines
已经制备了新的荧光四嗪并评估了它们的电化学和荧光效率。发现荧光的出现以及波长强烈依赖于取代基,取代基必须是带负电的杂原子。这已通过计算研究得到合理化,该研究表明关键因素是 HOMO 的性质,它决定了荧光的存在与否。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
