The heat is on : A Cu 5 metal cluster presents distinctive photophysical properties that result in a temperature‐dependent fluorescent quantum yield and excited‐state lifetime between −45 and +80 °C, both in solution and as a solid. Unprecedented accuracy in temperature determination by fluorescence measurements was achieved with this complex, thus making it suitable for applications in, for example, biology and (nano)materials research.
