Bulk approaches to studying heterogeneous systems obscure important details, as they
report average behavior rather than the distribution of behaviors in such environments …

Traditional fluorogens with aggregation-induced emission (AIEgens) generally exhibit strong
luminescence with monotonous wavelengths in the aggregated state, whereas apparent …

We report measurements of excitation and emission spectra of single, polymer-embedded,
perylene dye molecules at room temperature. From these measurements, we can derive the …

Single molecule (SM) methods are able to resolve structure related dynamics of guest
molecules in liquid crystals (LC). Highly diluted small dye molecules on the one hand …

Single molecule tracer diffusion studies of evaporating (thinning) ultrathin tetrakis-2-ethyl-
hexoxysilane (TEHOS) films on silicon with 100 nm thermal oxide reveal a considerable …

We performed polarized fluorescence emission studies of Nile Red (NR) in poly (methyl
methacrylate)(PMMA), poly (ethyl methacrylate)(PEMA), and poly (butyl …

Structure and dynamics at soft-matter interfaces play an important role in nature and
technical applications. Optical single-molecule investigations are noninvasive and capable …

We explore the distribution and shape of single molecule spectra at room temperature, when
embedded in a polymer host. Multicolour excitation and emission spectroscopy is …

In addition to the commonly observed single molecule fluorescence intensity fluctuations
due to molecular reorientation dynamics, a perylene bisimide-calixarene compound (1) …
