The optoelectronic and interfacial properties of the synthesized single fluorine-substituted parent molecule (T3-pF) (Yi C, <em>et al.</em> Angew. Chem., Int. Ed., 2023, 62: e202300314) and ten newly designed molecules were investigated using density functional theory (DFT) and time-dependent DFT (TD-DFT) methods. Results indicated that the position of fluorine substitution had a more significant impact on hole mobility than the number of substitutions. The newly designed molecules T3-mF, T3-2F-C, and T3-3F-B exhibited the highest hole mobility in mono-, di-, and tri-fluorine-substituted molecules, all of which showed approximately twice the hole mobility of the parent HTM T3-pF. Additionally, <em>ortho</em>-fluorine substituted molecules demonstrated greater advantages in intramolecular charge transfer. The calculations of interfacial performance revealed that anchoring more fluorine sites on Pb can enhance interface interactions (an increase in adsorption energy by up to 0.5 eV) and promote hole transfer between the HTM and perovskite substrates (a doubling of the Bader charge). Among all the HTMs studied, the trifluorinated molecule T3-3F-B exhibited a good balance between bulk phase charge transfer and interfacial properties, with hole mobility and Bader charge being about twice that of the parent molecule.

The traditional hydrothermal technique was followed in the preparation of cuboid shaped nanoparticles. The as-synthesized sample was characterized well <em>via</em> powder X-ray diffraction (PXRD) and transmission electron microscopy (TEM) studies revealing crystallite and particle sizes of ∼51 and ∼96 nm, respectively. Thermal variation of magnetization [<em>M</em>(<em>T</em>)] suggests creation of a canted antiferromagnetic (AFM) ground state with multiple magnetic transitions around 79, 50 and 11 K. Sizable orbital moment contribution has been validated from the mismatch between the experimental value and the theoretical estimation of the Curie–Weiss moment. Cooling field induced metastability below the first order magnetic transition and the explicit signature of the magneto-caloric-effect in terms of the change in entropy are two noteworthy features in this system. Below the ordering temperature, a substantial amount of EB (with EB field (<em>H</em><small>_E</small>) = 800 Oe at 3 K with a 40 kOe cooling field) has been demonstrated through the shift in the magnetic hysteresis (<em>M</em>−<em>H</em>) loop when cooled in an external magnetic field.

First reported by Ifor D. W.

In this work, OLPL that occurs upon doping CzPhAP in PPT/TPBi systems with charge-separation features was theoretically investigated to understand the essence of transformation from TADF to OLPL and to provide insights for further research. Theoretical results of this study revealed that OLPL emission from CzPhAP:PPT/TPBi systems proceeded <em>via</em> a double-luminescence mechanism.
