Novel cool white-luminescent hybrids through host–guest assembly of 6-hydroxybenz[de]anthracen-7-one and europium ion exchanged zeolite L

Zeolite L (ZL) is functionalized with europium ions through ion exchange and then 6-hydroxybenz[de]anthracen-7-one (HBAO) ligand is fabricated with coordination to Eu3 + by a so-called gas disperse (so-called ship-in-bottle) method. It is worthy pointing out that the europium hybrids show emission of both europium ion and HBAO, which can be integrated to show close white luminescence. This result provides a useful path to obtain white emissive lanthanide hybrids.
