合成了新的荧光四嗪化合物，并对其电化学性质和荧光效率进行了评价。发现荧光的发生以及波长强烈依赖于取代基，取代基必须是电负性杂原子。这已经通过一项计算研究得到了合理化，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。((C)Wiley-VCH Verlag GmbH & Co. KGaA，69451魏因海姆，德国，2009）
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 the existence or not of fluorescence.
