Abstract Gas sensors are pivotal for environmental monitoring and medical diagnostics but usually face the sensitivity-stability trade-off in trace-gas detection. Conventional sensitivity-enhancement strategies rely on reactive surface modifications, which may risk long-term stability, whereas inefficient gas-solid interaction time limits detection sensitivity.

1. Introduction Click to copy section linkSection link copied! In recent decades, crystalline polynuclear metal complexes have gained global attention for their fascinating physicochemical properties and esthetical appearance, for example in the fields of luminescence, electrochemistry, magnetism, and catalytic properties. (1−5) The properties of the crystalline materials are determined not only by their structure but also by the shape, size, and so on.
