Carbazole-functionalized Chichibabin diradicaloids with redshifted absorption and enhanced photoluminescence.

Abstract

Organic radicals and diradicaloids that are both stable and luminescent are promising candidates for molecular qubits in quantum technologies. Here we report two new carbazole-functionalized Chichibabin diradicaloids that in comparison to the parent compound TTM-TTM exhibit a 50 nm bathochromic shift of absorption and a 2-3-fold increase in PLQY.
