In the quest to develop artificial light-harvesting systems (LHSs) with high energy transfer efficiency, hydrazone ligands L1–L2 and their –BF₂ complexes (BODIHYs; B1 and B2) have been synthesized. Ligands L1 and L2 and the BODIHYs have been thoroughly characterized by various techniques (¹H, ¹³C, ¹¹B, and ¹⁹F NMR, ESI-MS, UV-vis and fluorescence). Further, the BODIHYs (B1 and B2) have been utilized as a new platform for artificial LHSs. It has been categorically shown that efficient artificial LHSs can be achieved by combining AIEgens B1 and B2 with rhodamine B (RhB) under aqueous conditions. In these systems B1 and B2 serve as a donor while RhB as an acceptor. The calculated energy transfer efficiency and antenna effect for the BODIHYs in combination with RhB came out to be appreciably high (B1 = 68%, 28.7; B2 = 80%, 35.5) at a donor/acceptor ratio of 25 : 1.

基于二氟化硼（BF2）complex配合物（BODIHYs）的人工光收集系统（LHS）

为了开发具有高能量转移效率的人造光收集系统（LHS），已经合成了ligand配体L1-L2及其-BF ₂配合物（BODIHY；B1和B2）。配位体L1和L2和BODIHYs已经通过各种技术（被彻底其特征在于^1个H，¹³ C，¹¹ B和¹⁹ F NMR，ESI-MS，UV-vis和荧光）。此外，BODIHY（B1和B2）已被用作人工LHS的新平台。已经明确表明，在水性条件下，通过将AIEgens B1和B2与若丹明B（RhB）结合可以实现有效的人工LHS 。在这些系统中，B1和B2充当供体，而RhB充当受体。在供体与受体的比例为25：1的情况下，计算出的BODIHY与RhB的能量转移效率和天线效应相当高（B1 = 68％，28.7; B2 = 80％，35.5）。
