To investigate the properties of intrinsic RTP from solution to aggregates, the PL properties of dendrimers in dilute THF/water solution were measured. The PL intensity of HCBPSF exhibited a steady decrease with adding water to fractions (fw) of 60%, indicating the twisted intramolecular charge transfer (TICT) property. However, as the fw increased to 90%, the PL emissions increased significantly by orders of magnitude, indicating a pronounced aggregation-induced emission 37 phenomenon (Supplementary Fig. ). Concurrently, the PL lifetimes also exhibited a substantial increase from 3.2 to 28.0 ms with an increasing degree of aggregation (Fig. ), indicating AIPE behaviors. Similar trends were observed in the THF/water solution of TCBPSF (Supplementary Fig. ). The knr of TCBPSF and HCBPSF, respectively were calculated to be 547 and 314 s -1 in the 10% water solution, and significantly decreased to knr of 43 and 34 s -1 in the aggregated state with 90% water (Supplementary Figs. 14-17&Table S1-3), indicating restricted intramolecular motions and the blocking of nonradiative pathways with the degree of aggregation increases. These findings highlight the crucial role of aggregated states in promoting and amplifying the intrinsic RTP properties of the dendrimers, indicating their promising application prospects in aggregate states.
