Research Abstract

We studied the unique properties of polymer chains confined in the nanochannels of metal-organic frameworks(MOFs). Incorporation of polyethylene glycol(PEG) into the MOF nanochannels enabled observation of thermal transitions of only a few chain assemblies, for the first time. Fluorescent oligomers accommodated in a flexible MOF showed conformational variations concurrently with the host structural change during gas and vapor adsorption processes, which is a key for advanced fluorescent detection of molecules.
