Novel fluorophores, 3,4,6-triphenyl-α-pyrone derivatives, were synthesized and their spectroscopic properties have been investigated. In the solid state they show intense greenish-yellow fluorescence, but not in solution. It is concluded that the 6-phenyl group is fixed at an angle of about 26° to the pyrone plane in the solid state by molecular packing and this fixation is required for this unique fluorescent property.
我们合成了新型荧光团--3,4,6-三苯基-α-吡喃酮衍生物,并研究了它们的光谱特性。在固态下,它们显示出强烈的黄绿色荧光,但在溶液中则没有。结论是在固态下,6-苯基通过分子填料与吡喃酮平面成约 26°角固定,这种固定是这种独特的荧光特性所必需的。
