Abstract
Ionogel is an emerging hybrid material which is usually constructed by confined an ionic liquid into some special matrices, and it is expected to have great potential applications in the field of electrolyte materials, opticalelectric materials and so on. Here, a terbium complex covalently modified graphene was introduced into the 1-butyl-3-methylimidazolium bis[(trifluoromethyl)sulfonyl]imide ionic liquid based ionogel matrix. The resulted material is a kind of novel photoluminescent hybrid material which has a transparent appearance and shows strong green under the UV light. The photoluminescent properties of the ionogel has been measured in details, revealing a broad excitation spectra, line-like emission spectra and long luminescence lifetimes which make it great potential applications in the preparation of optical-electric devices, together with the intrinsic conductive property of the embedded ionic liquid.
Highlights
The nanoparticle composited gel materials which are built by incorporating a nanoparticle into the polymer networks derived gel systems have arouse the general attentions [12]
It has been proved that the introduction of lanthanide complexes into an ionogel matrix would provide a new opportunity to design and synthesis novel hybrid materials, which is hoped to have the outstanding luminescent properties of lanthanide complex and the good ionic conductivity comes from ionic liquids [14,15,16]
The BPC modified graphene was synthesized from the Graphene oxide (GO) as follows: Firstly, 100 mg GO was dispersed in 100 mL anhydrous solvent of DMF and dichloromethane (DCM) (v:v = 1:1) by means of supersonic vehicle, 1.5 mmol DCC and 1 mmol DMAP were added to active it for 1 h in ice bath
Summary
The nanoparticle composited gel materials which are built by incorporating a nanoparticle into the polymer networks derived gel systems have arouse the general attentions [12] This combination may result in a synergistic property enhancement of each component, and even holds the promise of providing a multifunctional hybrid materials with applications in diverse fields such as nano-medicine, optoelectronic devices, drug delivery and so on. It has been proved that the introduction of lanthanide complexes into an ionogel matrix would provide a new opportunity to design and synthesis novel hybrid materials, which is hoped to have the outstanding luminescent properties of lanthanide complex and the good ionic conductivity comes from ionic liquids [14,15,16]. The photoluminescent properties of the hybrid ionogel had been measured in details
