rylenes! Soluble and stable tetracyanoquaterrylenequinodimethane (QR‐CN) and tetracyanohexarylenequinodimethane (HR‐CN) were synthesized. QR‐CN has a closed‐shell quinoidal structure in the ground state, whereas HR‐CN has a singlet biradical ground state. Both compounds showed very strong one‐photon and two‐photon absorption in the NIR range.
