White light emitting materials have broad application prospects in fields such as displays, lighting devices, etc., but developing such materials faces considerable challenges. In this study, 1,3,5-tris[4-(pyridine-4-butyl)phenyl]benzene derivative (BTPY) was synthesized and a supramolecular assembly with AIE properties named BTPY@Q[7] was prepared with cucurbit[7]uril (Q[7]). Furthermore, by adding rhodamine 6G (R6G) to it, and controlling its ratio with R6G, a dual-emission white light system (0.33, 0.33) was synthesized and used for white light emitting materials as well as anti-counterfeiting fields. In addition, based on the BTPY@Q[7]-R6G system, a light harvesting system in aqueous phase was constructed, with an energy transfer efficiency (Φ) of 26.19 % and an antenna effect (AE) of 10.21. Interestingly, the supramolecular self-assembly can also be used as a fluorescent probe, specifically recognize Fe(CN) ions in water, with a detection limit of 2.5 × 10 M.
白色发光材料在显示器、照明设备等领域具有广阔的应用前景，但开发此类材料面临着相当大的挑战。在本研究中，合成了1,3,5-三[4-(吡啶-4-丁基)苯基]苯衍生物（BTPY），并与葫芦[7]脲（Q[7]）制备了具有聚集诱导发光（AIE）性质的超分子组装体BTPY@Q[7]。此外，通过向其中加入罗丹明6G（R6G）并控制其与R6G的比例，合成了双发射白光体系（0.33, 0.33），并将其用于白色发光材料以及防伪领域。另外，基于BTPY@Q[7]-R6G体系构建了水相中的光捕获体系，能量转移效率（Φ）为26.19%，天线效应（AE）为10.21。有趣的是，该超分子自组装体还可作为荧光探针，特异性识别水中的Fe(CN)离子，检测限为2.5×10 M。
