摘要:A method of synthesizing zinc oxide nanoparticles includes mixing an aqueous solution of a zinc precursor and an aqueous solution of L-tryptophan to form a reaction mixture and heating the reaction mixture to a temperature of at least 100° C. to produce a dry powder. The method further includes calcining the dry powder to obtain the zinc oxide nanoparticles. The zinc oxide nanoparticles have an average particle size of 155 nm or less. Further, the zinc oxide nanoparticles are substantially spherical and include mesopores with a total pore volume of 0.1 to 0.5 cm3/g.

摘要:Process for the preparation of a polyazamacrocycle substituted with at least one aryl or heteroaryl group comprising reacting at least one unsubstituted polyazamacrocycle with at least one halogenated aryl or heteroaryl compound. Said polyazamacrocycle substituted with at least one aryl or heteroaryl group may advantageously be used in the synthesis of anionic or cationic complexes and/or of supramolecular adducts useful in the construction of luminescent solar concentrators (LSCs), which in their turn may advantageously be used together, for example, with photovoltaic cells (or solar cells), or with photoelectrolytic cells, in solar devices (i.e. devices for exploiting solar energy). Moreover, said polyazamacrocycle may be used in other fields such as, for example, the analytical field, the medical or biomedical field, the biological field, the field of detergents (both for household use and for personal care use).
