Marinova, Maya published the artcileSynthesis, Resolution, Configurational Stability, and Properties of Cationic Functionalized [5]Helicenes, Safety of 1,3-Dimethoxybenzene, the main research area is helicene dye preparation resolution configurational stability.
A straightforward approach to the synthesis of two different series of cationic [5]helicenes has been achieved including, in dioxa series, the possibility to introduce aromatic functional groups at the periphery of the helical structure. While photophys. study highlights that the introduction of aryl substituents at position 23 of the helical moieties has a negligible impact on the optical properties, styryl substituents allow a welcoming extension of the conjugation pathways. Finally, a red shift of the optical properties was evidenced upon introduction of nitrogen atoms in the helicene scaffold, leading to particularly good fluorescence efficiencies in the red domain for a helicenic dye. Detailed information on racemization kinetics was collected for the most stable species upon direct high-performance liquid chromatog. (HPLC) resolution or, when configurational lability was too high, through VT-HPLC anal. on the chiral stationary phase (ΔG‡ values ranging from 85.0 to 137.1 kJ·mol-1 and above).
Journal of Organic Chemistry published new progress about Activation enthalpy (for racemization). 151-10-0 belongs to class isoquinoline, name is 1,3-Dimethoxybenzene, and the molecular formula is C8H10O2, Safety of 1,3-Dimethoxybenzene.
