The rational improvement of photophysical properties can be highly valuable for the discovery of novel organic fluorophores. Using our new design strategy guided by the oscillator strength, we developed a series of full‐color‐tunable furoindolizine analogs with improved molar absorptivity through the fusion of a furan ring into the indolizine‐based Seoul fluorophore. The excellent correlation between
光物理性质的合理改善对于发现新型有机荧光团可能非常有价值。使用我们以振荡器强度为指导的新设计策略,我们开发了一系列全色可调呋喃吲哚嗪类似物,通过将呋喃环融合到基于吲哚嗪的首尔荧光团中,提高了摩尔吸收率。可计算值(振荡器强度和理论上的S 0 –S 1能隙)与光物理特性(摩尔吸收率和发射波长)之间的极好的相关性证实了我们设计策略的有效性。
