The excited-state dynamics of pentacene derivatives with stable radical substituents were evaluated in detail through transient absorption measurements. The derivatives showed ultrafast formation of triplet excited state(s) in the pentacene moiety from a photoexcited singlet state through the contributions of enhanced intersystem crossing and singlet fission. Detailed kinetic analyses for the transient absorption data were conducted to quantify the excited-state characteristics of the derivatives.
通过瞬态吸收测量详细评估了具有稳定自由基取代基的并五苯衍生物的激发态动力学。这些衍生物通过增强的系间窜越和单重态裂变，从光激发的单重态超快形成并五苯部分的三重激发态。对瞬态吸收数据进行了详细的动力学分析，以量化衍生物的激发态特性。
