Some pyrazine dyes based on the same chromophoric system with different steric nature were synthesized to evaluate the correlation between solid-state fluorescence and molecular arrangement. It was confirmed that the solid-state fluorescence is significantly correlated with the prevention of complete stacking between chromophoric systems in the crystalline state. This result suggests that the introduction of bulky substituents to fluorescent dyes should be made on substantial positions for preventing the complete stacking between the chromophoric systems on the basis of the crystal structure.
合成了一些基于相同色基系统但具有不同立体性质的吡嗪染料,以评估固态荧光与分子排列之间的相关性。结果确认,固态荧光与晶态下色基系统之间完全堆叠的防止显著相关。这一结果表明,为了防止根据晶体结构的色基系统之间的完全堆叠,应在重要位置引入笨重取代基到荧光染料中。
