Recently I am researching about ONE HUNDRED YEARS; CHIROPTICAL PROPERTIES; CHROMATOGRAPHIC RESOLUTION; STEREOSELECTIVE SYNTHESES; OPTICAL-PROPERTIES; HELICENE; DYES; ELECTROCHEMILUMINESCENCE; DERIVATIVES, Saw an article supported by the Swiss National Science FoundationSwiss National Science Foundation (SNSF)European Commission; SCIEX program; SCOPES programSwiss National Science Foundation (SNSF) [IZ73ZO_128013]. Formula: C8H10O2. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Marinova, M; Pascal, S; Guenee, L; Besnard, C; Shivachev, B; Kostova, K; Villani, C; Franzini, R; Dimitrov, V; Lacour, J. The CAS is 151-10-0. Through research, I have a further understanding and discovery of 1,3-Dimethoxybenzene
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 photophysical 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 chromatography (HPLC) resolution or, when configurational lability was too high, through VT-HPLC analysis on the chiral stationary phase (Delta G double dagger values ranging from 85.0 to 137.1 kJ.mol(-1) and above).
