A water-soluble cationic pillar[5]arene (CWP5) without lager conjugated construction was first reported as a novel pillar[5]arene-based aggregation-induced emission luminogen (AIEgen), which showed a remarkable aggregation-induced emission (AIE) with the concentration increasing. The AIE effect of CWP5 has affected by different solvent, it had the lowest critical aggregation concentration (CAC) value and highest fluoresence emission intensity in DMSO solution. Simultaneously, CWP5 can serve as a chemosensor for the successively fluorescent detection of Fe3+ and F-/H2PO4- with high sensitivity and selectivity. A rewritable portable test kit made from CWP5 provides a possibility to on-site detection and manufacture of encryption and decryption materials. (C) 2019 Elsevier B.V. All rights reserved.
