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.

An efficient Ni‐based heterogeneous catalyst from pine needles urban waste valorization was designed and developed with a resource recycling strategy. The Ni/PiNe catalyst was fully characterized and tested in the Suzuki‐Miyaura coupling under microwave irradiation. Although Ni is a promising candidate for replacing Pd‐based catalytic systems, it generally requires a high catalyst amount and the exploitation of ligands and additives to enhance the reaction rate. On the contrary, with our new Ni/PiNe, 30 different products were efficiently synthesized with an isolated yield of up to 93%, using a very low catalyst amount and in the absence of ligands. Furthermore, the Ni/PiNe catalyst also showed good durability for consecutive cycles and an impressive TON value (1140). In addition to the catalytic efficiency in short reaction time and to the stability and durability under MW irradiation, the Ni/PiNe allowed for further optimization, achieving a low E‐factor value (14.0), thus highlighting the potential in further reducing the waste and costs associated to the process.
