Abstract
The in-depth location and orientation of membrane probes and drugs inserted in lipidic bilayers are regarded important key-properties that cannot be overlooked during molecular design and synthesis. Several spectroscopic phenomena (e.g. excitonic interaction) and molecular recognition (e.g. ligand-receptor interaction) depend on these properties. However, molecular orientation in lipidic membranes is scarcely addressed. This paper overviews some of the most important techniques and methodologies used to study orientation of molecules relative to the surrounding lipidic matrix, namely: FTIR linear dichroism, UV-Vis linear dichroism, Time-resolved fluorescence anisotropy, NMR, and Surface Plasmon Resonance.
Keywords: receptor-mediated processes, biological membranes, infrared spectroscopy, internal reflection element (ire), linear dichroism, langmuir-blodgett (lb) technique, polyene macrolide, phospholipids

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
