“…For the synthesized luminophors, the highest occupied molecular orbit (HOMO) and the lowest unoccupied molecular orbit (LUMO) energy levels were observed in the range 5.56–5.61 eV and 2.79–2.81 eV, respectively. E g calculated from the CV were in range 2.72–2.82 eV, which was in close proximity to the optical band gap …”

“…However, as the Pery concentration increased from 1 × 10 −3 to 1 × 10 −2 to 1 × 10 −1 mole Pery per mole 2‐NP, exciplex formation was favoured and exciplex emission was observed in the 480–650 nm wavelength range, peaking at 570 nm. This exciplex emission was therefore concentration dependent, as the Pery concentration increased, the exciplex emission became more intense …”

Several perylene (Pery)‐doped 2‐naphthol (2‐NP) (Pery/2‐NP) luminophors were prepared using conventional solid‐state reaction techniques. Energy transfer in the excited state was examined using fluorescence spectroscopy and cyclic voltammetry. Fluorescence studies revealed exciplex formation by Pery in the form of structureless and broad spectra at higher concentrations with monomer quenching of 2‐NP; a broad green emission was observed in the range 500–650 nm, peaking at 575 nm. Structural properties and thermal stability were analyzed using X‐ray diffraction, scanning electron microscopy and TGA‐differential scanning calorimetry. Highest occupied molecular orbital and lowest unoccupied molecular orbital energy levels were observed in the range 5.56–5.61 eV and 2.79–2.81 eV, respectively with a 2.77–2.82 eV band gap. The present study reveals these to be probable candidates for hole‐transporting materials suitable in optoelectronics.
