CVD of Ionic Liquids @Angewandte Chemie!

Film deposition and high-resolution patterning of ionic liquids (ILs) remain a challenge, despite a broad range of applications that would benefit from this type of processing.

In this work, we demonstrate for the first time the chemical vapor deposition (CVD) of ILs. The IL-CVD method is based on the formation of a non-volatile IL through the reaction of two vaporized precursors. Ionogel micropatterns can be easily obtained via the combination of IL-CVD and standard photolithography, and the resulting microdrop arrays can be used as microreactors.

The IL-CVD approach will facilitate leveraging the properties of ILs in a range of applications and microfabricated devices.

Photoswitching in anthracene loaded MOFs @EJIC!

The confinement of luminescent guest molecules in porous host materials can induce photophysical properties different from either component in isolation.

In this work, we present the photophysical behavior of anthracene and its substituted analogs in a series of metal-organic frameworks (MOFs) and inorganic molecular sieves. Fluorescence photoswitching of the guest molecules through photoinduced dimerization is observed only in MOFs with a favorable pore volume and geometry.
