The chemistry of low-valent bismuth compounds has recently unlocked new concepts in catalysis and unique electronic structure fundamentals. In this work, we describe the synthesis and characterization of a highly reduced bismuth salt featuring a cationic core based on three contiguous Bi(I) centres. The triatomic bismuth-based core exhibits an electronic configuration that mimics the canonical description of the archetypical carbon-based π-allyl cation.

- Recent studies on stable monocoordinated organobismuthinidenes have revealed unique chemical and electronic structures.
- Quantum chemical calculations indicated that Bu-MFluind-Bi(I) has a triplet ground state with a significant zero-field splitting (ZFS) greater than 4500 cm, which had not been verified experimentally before.
- This research successfully measured a ZFS of 5422 cm using magneto-optical infrared spectroscopy, marking the highest ZFS recorded to date.
3D printing, also known as additive manufacturing, holds immense potential for rapid prototyping and customized production of functional health-related devices. With advancements in polymer chemistry and biomedical engineering, polymeric biomaterials have become integral to 3D-printed biomedical applications. However, there still exists a bottleneck in the compatibility of polymeric biomaterials with different 3D printing methods, as well as intrinsic challenges such as limited printing resolution and rates.
