A novel supramolecular organogel based on acylhydrazone functionalized pillar[5]arene acts as I- responsive smart material

Abstract

A novel organic gelator (PZ) has been synthesized by rationally connected a pillar[5]arene moiety and a bis(hexadecyloxy)phenyl functionalized acylhydrazone moiety. The PZ could self-assemble into supramolecular polymer and form stable organogel (OPZ) in cyclohexanol by multi-self-assembly driving forces such as C-H∙∙∙π, π∙∙∙π, vdW forces and hydrogen bonding interactions. The organogel (OPZ) shows blue aggregation-induced emission (AIE). Interestingly, the organogel OPZ could sense iodide ion (I-) in gel-gel state with high selectivity and sensitivity. The detection limit of the OPZ for I- is 9.4×10-8 M, indicating the high sensitivity to I-. Furthermore, a thin film based on the OPZ was prepared, which could be used as a smart material for detecting I- as well as a fluorescent security display materials.
