Abstract

1D nanoribbons with supramolecular controllable handedness are constructed by the co-assemblies of porphyrin tubular cage (PTC) with polylysine (PL) upon multiple intermolecular forces at the air/water interface. Depending on the outstanding stimuli-responsive performance of aggregating hierarchical nanoribbons, the enantiomers of theanine are clearly discriminated through the relative fluorescence intensity of co-assembling system. It is revealed that the enantioselective mechanism originate from the quite disparate intermolecular interactions between co-assemblies and theanine isomers induced selective adsorption by means of experimental characterization combined with molecular simulations. This study not only helps to further understand the multiple interaction within co-assembling system, but also provides a novel strategy for enantioselective sensing platform with controllable handedness.

期刊介绍： The Microchemical Journal is a peer reviewed journal devoted to all aspects and phases of analytical chemistry and chemical analysis. The Microchemical Journal publishes articles which are at the forefront of modern analytical chemistry and cover innovations in the techniques to the finest possible limits. This includes fundamental aspects, instrumentation, new developments, innovative and novel methods and applications including environmental and clinical field. Traditional classical analytical methods such as spectrophotometry and titrimetry as well as established instrumentation methods such as flame and graphite furnace atomic absorption spectrometry, gas chromatography, and modified glassy or carbon electrode electrochemical methods will be considered, provided they show significant improvements and novelty compared to the established methods.
