Advanced material architecture can be used to develop tailor-made interfaces for innovative and selective sensor platforms. An intricate mesh structure of manganese oxide nanowires and carbon nanotubes was synthesized. Further, the mesh was strengthened by a molecularly imprinted network to generate template cavities and impart selective recognition. Termed as MIP@MnO:CNT, this mesh structure was used as the receptor interface for microarray transducers. The unique hybrid composition and morphology enhanced binding performance for detection of para-nitrophenol (P-NP), an important pollutant. The sensor showed exceptional sensitivity towards P-NP monitoring with a limit of detection of 3 nM (S/N = 3). Benefitted from the imprinting strategy, the designed sensor exhibited 85-99% selectivity when compared to other aromatic compounds. Moreover, the designed interface was able to detect P-NP in water samples. As demonstrated in this study, other chemical compositions and morphology of multidimensional materials can be crafted for the improved and specific detection of analytes.

Three novel polymeric Mn(II) acetate derivatives, identified as {[Mn2.5(OH)(CH3COO)4]·0.5CH3OH·0.5CH3CN}n (1), {[Mn3(CH3CO O)6]·0.5CH3CN}n (2) and {Mn1.5K(CH3COO)4}n (3), have been successfully prepared by systematically adjusting the ratio of reactants and using the 2‐mercapto‐5‐methyl‐1,3,4‐thiadiazole (Hmmt) as the template agent. These three complexes can be regarded as the different crystalline forms of Mn(CH3COO)2 under different reaction conditions. Single‐crystal X‐ray diffraction analyses revealed that 1‐2 feature the unique three‐dimensional (3D) framework. For 3, it displays a 2D structure, which is further assembled to form a 3D extended network via the weak hydrogen bond interactions. Magnetic studies confirmed that 1 and 2 show antiferromagnetic interactions, and 1 displays a long‐range ordering phase below the critical temperature (Tc) of 7.8 K. In addition, magnetization data collected for 1‐2 yield low magnetic entropy changes, which can be attributed to the strong antiferromagnetic interactions among the Mn(II) centres.
