Synthesis and Chiroptical Properties of a Saddle-Shaped Quadruple Helicene with a Cyclooctatetrapyrrole Core
A quadruple helicene with a cyclooctatetrapyrrole core was synthesized via a simple Ullmann reaction. Its single-crystal structure exhibits a saddle shape. The compound shows fluorescence emission with λ<sub>em</sub> = 575 nm and good chiroptical properties, including a dissymmetric absorption factor (|<i>g</i><sub>abs</sub>|) of 5.84 × 10<sup>-3</sup> and a dissymmetric emission factor (|<i>g</i><sub>lum</sub>|) of 1.21 × 10<sup>-2</sup>.
