我们对四苯氧基取代的苝双酰亚胺衍生物的光物理性质进行了详细研究。探针分子固定在十六烷的 Shpol'skii 基质中，并在低温下通过单分子光谱进行研究。通过使用单分子光谱技术，我们揭示了三重态亚态动力学和荧光量子产率，并提供了 S-1-S-0 跃迁偶极矩的估计。
We present a detailed study of the photophysical properties of a tetraphenoxy-substituted perylene bisimide derivative. The probe molecules were immobilized in a Shpol'skii matrix of hexadecane and investigated by single-molecule spectroscopy at cryogenic temperatures. By using single-molecule spectroscopic techniques we reveal the triplet substate kinetics and the fluorescence quantum yield, and we provide an estimate for the S-1-S-0 transition dipole moment.
