摘要：

A simple and efficient approach leading to a well functionalized helically chiral pi-conjugated system is reported. Optical resolution of racemic helicene has been well accomplished affording both enantiomers (+)- and (-)-4 in high optical purity and their chiroptical properties were experimentally evaluated. Based on electronic circular dichroism (ECD) absolute configurations of dextrorotary and laevorotatory antipodes were assigned as P and M, respectively. Photophysical properties of the helical compound have been also examined in solutions and show a remarkable behaviour. (C) 2018 Elsevier B.V. All rights reserved.
