报告摘要：

Here, we will first introduce an innovative crystal engineering strategy that addresses a longstanding challenge in organic semiconductor materials for photonic and electronic applications: promoting synergistic host-guest interactions within doped crystalline matrices to enhance or tune properties, particularly for long-lived organic room temperature phosphorescence (RTP). Specifically, we introduce a new strategy termed dopant-tailored matrices, which is based on the rational design of crystalline host matrices with predefined packing motifs that enable synergistic interactions with dopants.1 We validate this approach by focusing on the prototypical carbazole–benzoindole host–dopant system and demonstrating that engineered carbazole-based matrices can exhibit long-lived RTP when doped with benzoindole derivatives. Through this work, we not only advance the structural principles underlying dopant-induced RTP but also provide a generalizable strategy for the rational design of pristine and doped organic semiconductor crystals with tailored optoelectronic properties.

Second, from our previous works, we will present our recent results on the still under debate RTP mechanism in host-guest systems. We demonstrate that the triplet excited state located on the benzoindole guest is significantly lower in energy than charge-separated states between the host and the guest. This strongly suggests that an energy-transfer from the host to the guest, rather than charge-transfer, is involved in the RTP mechanism.
