title: Core-extended terrylene tetracarboxdiimide: synthesis and chiroptical characterization.
abstract: The novel 1,16:6,7:8,9:14,15-tetranaphthoterrylene tetracarboxdiimide was synthesized via a straightforward route, yielding optically active atropisomers with a high racemization barrier. Absorption, fluorescence, and circular dichroism measurements revealed high absorption coefficients and fluorescence quantum yields and enabled the stereochemical assignment in combination with quantum mechanical calculations.
