Keywords: charge carrier mobility; HOMO–LUMO energy levels; photophysical characterization; TFT devices; tris-(1-oxo-1H-phenalen-9-olate)aluminum(III); Introduction Since the field of organic electronics has emerged, interest in organic semiconductors (OSCs) has substantially increased [1]. The efficiency

• very reason we have synthesized and studied the phenalenyl-based alternative, OSC tris(1-oxo-1H-phenalen-9-olate)aluminum(III) (Al(Op)3) (see Figure 1), which is formed by ligands with an extended aromatic system. The expected result is an increased capability to accept and efficiently delocalize

• calculation of reorganization energy, a def2-TZVP [47] basis set was used. Tris(1-oxo-1H-phenalen-9-olate)aluminum(III) (Al(Op)3) structure. H atoms are omitted for clarity. Cyclic voltammogram for Al(Op)3 recorded at room temperature in CH2Cl2 solution using TBAPF6 as the electrolyte and ferrocene as an
