Abstract: This study presents the design and synthesis of two types of tetraphenylethylene-based multicomponent metallacages through coordination-driven self-assembly. We compared the luminescent properties and quantum yields of tetraphenylethylene in its three-dimensional structural form with those of its monomeric state, both in solution and solid state. Furthermore, utilizing the metallacages as the focal point of our research, we investigated their high quantum yields and favorable solution processing characteristics for their application as coatings in blue organic light-emitting diodes (LEDs) to develop white light-emitting diodes.
