Coordination polymer microrods of [Cu(μ 2 ‐L)(H 2 O)] n ( CuL ) (H 2 L = thiazolidine‐2,4‐dicarboxylic acid) were synthesized via a simple and versatile precipitation method at room temperature. Chemiresistive sensory devices based on these CuL microrods were prepared to investigate the gas sensing performance for the first time. The CuL microrod gas sensor exhibits reliable linear response towards trimethylamine (TMA) vapor at 95 °C with high response, fast response‐recovery, and good selectivity. Notably, as low as 1 ppm TMA can be well detected with high response value ( S r = 9.2). This work provides an ideal candidate material for monitoring TMA vapor and further develops a new promising application for coordination polymer micro‐/nano‐structures.
