A Recyclable Dynamic Semiconducting Polymer Consisting of Pauli-Paramagnetic Diradicaloids Promoted and Stabilized by Catechol-Boron Coordination

Coordination between 5, 5′, 6, 6′-tetrahydroxyindigo (4OH-ID) and Boron tribromide unexpectedly affords a novel dynamic covalent polymer, namely P(ID-O-B), consisting of alternating indigo and indigo diradicaloid units. Catechol-boron dynamic bond...
