Luminescence Characteristics

A metal-free aromatic compound exhibiting thermally activated delayed fluorescence as well as circularly polarized luminescence (CPL) with dissymmetry factors of 10−3 is reported. This compound shows a sign inversion between its circular dichroism signal and CPL, which is caused by a large conformational change upon photoexcitation.
