alkyl chains on their amino groups were newly synthesised and their fundamental properties investigated, including their derivatives, focusing on liquefaction at room temperature. The butyl, pentyl, hexyl, heptyl, octyl, and dodecyl substitutions realised liquefaction of the dye chromophore. These liquid dyes exhibited relatively good fluorescent properties in the liquid state. The dodecyl derivative
新合成了六种氨基上具有中长链烷基链的2,5-二氨基-3,6-二氰基吡嗪染料,并研究了其基本性能(包括其衍生物),重点是室温下的液化。丁基,戊基,己基,庚基,辛基和十二烷基取代实现了染料发色团的液化。这些液体染料在液态下表现出相对良好的荧光性质。在衍生物中,十二烷基衍生物在液态中显示出最大的荧光效率,为0.59,并用于有机发光器件中。器件的开启电压为10 V时,有效的黄色EL发射在593 nm处达到峰值,而14 V时的最大亮度为336 cd / m 2。
