TL;DR: The results demonstrate that the broadband emission of (EDBE)PbBr4 single crystals and spin-coated films arises from a single ensemble and not from a set of distinct excited states with different emission wavelengths and lifetimes.

Ultrafast to Ultraslow Dynamics of a Langmuir Monolayer at the Air/Water Interface Observed with Reflection Enhanced 2D IR Spectroscopy
Chang Yan,Joseph E. Thomaz,Yong-Lei Wang,Jun Nishida,Rongfeng Yuan,John P. Breen,Michael D. Fayer +6 more
TL;DR: Reflection enhanced two-dimensional infrared (2D IR) spectroscopy on a carbonyl stretching mode of tricarbonylchloro-9-octadecylamino-4,5-diazafluorenerhenium(I) (TReF18) monolayer at two surface densities reveals that it takes the monolayers hours to reach macroscopic structural equilibrium.

Bulk-like and Interfacial Water Dynamics in Nafion Fuel Cell Membranes Investigated with Ultrafast Nonlinear IR Spectroscopy.
TL;DR: Comparison of the observed dynamics to those of AOT reverse micelles helps identify local interactions between water and sulfonate anions at the interface and among water molecules in the core and demonstrates that the well-known spherical cluster morphology of Nafion is not appropriate.

The influence of mesoscopic confinement on the dynamics of imidazolium-based room temperature ionic liquids in polyether sulfone membranes
TL;DR: The structural dynamics of a series of 1-alkyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide room temperature ionic liquids confined in the pores of polyether sulfone membranes with an average pore size of ∼350 nm and in the bulk liquids were studied.

The Influence of Water on the Alkyl Region Structure in Variable Chain Length Imidazolium-Based Ionic Liquid/Water Mixtures
TL;DR: The results suggest that phase separation in longer chain length BF4 RTILs is a consequence of their inability to undergo the reorganization of the alkyl regions necessary to accommodate high water concentrations.
