A novel impedimetric humidity sensor based on a one dimensional [Pb0.5(TAA)]n (HTAA = 3‑thiopheneacetic acid) coordination polymer

A 1D coordination polymer with formula of [Pb0.5(TAA)]n (noted as PbL, HTAA = 3-thiopheneacetic acid) was synthesized via a hydrothermal method. The PbL was then examined as a sensitive material based on an impedimetric humidity sensor. The PbL humidity sensor exhibited superior sensing performance.150
