摘要：Metal halide materials have recently drawn increasing research interest for their excellent opto-electronic properties and structural diversity, but their resulting rigid structures render them brittle and poor formability during manufacturing. Here we demonstrate a thermoplastic luminant hybrid lead halide solid by integrating lead bromide complex into tri-n-octylphosphine oxide (TOPO) matrix. The construction of the hybrid materials can be achieved by a simple dissolution process, in which TOPO molecules act as the solvents and ligands to yield the monodispersed clusters. The combination of these functional units enables the near-room-temperature melt-processing of the materials into targeted geometry by simple molding or printing techniques, which offer possibilities for fluorescent writing inks with outstanding self-healing capacity to physical damage. The intermarriage between metal halide clusters with functional molecules expands the range of practical applications for hybrid metal halide materials. Metal halide materials, known for their opto-electronic properties and structural diversity, face challenges due to rigidity, making them brittle and difficult to shape. We introduce a thermoplastic hybrid lead halide solid, formed by integrating lead bromide complex into a TOPO matrix. This enables near-room-temperature melt-processing, offering potential for self-healing fluorescent inks. image
