Light-controllable reflection wavelength of blue phase liquid crystals doped with azobenzene-dimers

A new series of azobenzene-dimers were synthesized and doped into the blue phase liquid crystals to broaden the temperature range of BPs. It is found that not only can the reflection wavelength of BPI be reversibly controlled but BPI can also be transform

Synthesis of [18F] Fluoroclofilium as a potential cardiac imaging agent for PET studies

N-4-(4-chlorophenyl)butyl-N,N-diethyl-7-[ 18F]fluoroheptylammonium ([18F]-fluoroclofilium) has been prepared as a potential cardiac imaging agent. For the synthesis of this radiolabelled ammonium salt, its tosyloxylated analogue was prepared as a precursor, and the non-radioactive fluorine analogue was synthesized as a reference compound. Radiofluorination was achieved by the treatment of N-4-(4-chlorophenyl)butyl-N,N-diethyl-7-(p-toluenesulfonyloxy)-heptylammonium p-toluenesulfonate with 18F- in the presence of Kryptofix-2.2.2 in acetonitrile.
