    Color Tunable Emission and Oxygen Sensing from a Discrete Europium−Pyrene Assembly
    (Wiley-VCH GmbH, 2023-08-14) O'Neil AT; Pope J; Harrison JA; Kitchen JA
    We report the synthesis of a new pyrene, dipicolinic acid-based ligand (L1H) and its corresponding multi-emissive and multifunctional europium complex [Eu(L1)3] that is capable of single component color switchable emission from red to blue and also white. At high concentration (10 mM) the single component system results in near pure white emission (CIE coordinates x,y=0.329, 0.324). Furthermore, the system showed ratiometric oxygen sensing with oxygen significantly quenching the pyrene centered emission but not the Eu3+ emission, resulting in an overall emission color change from blue to red on increasing oxygen content.

    Ultra-thin films of amphiphilic lanthanide complexes: multi-colour emission from molecular monolayers
    (Royal Society of Chemistry, 2021-08-21) O'Neil AT; Harrison JA; Kitchen JA
    We report the synthesis and Langmuir-Blodgett deposition of 4 brightly emissive lanthanide amphiphiles that can be co-deposited to give multi-emissive ultra-thin films where two, three and four distinct lanthanide emission profiles are observed. To the best of our knowledge, this is the first report of a four-component emissive Langmuir-Blodgett film.
