a) Simplified energy diagram showing the thermally assisted equilibrium between singlet and triplet excited states; chemical structure and X‐ray molecular structure of DPTZ‐DBTO2,.2CDCl3, CCDC‐1034115. b) HOMO and LUMO of DPTZ‐DBTO2, and S1 and T1 energies obtained from TD‐DFT calculations at B3LYP/6‐31G(d), as a function of the D–A–D relative dihedral angles, assuming that singlet and triplet excited state geometries are the same.
