摘要

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