“…Furthermore, the proper design and synthesis of these materials with optimal efficiency is still a challenge. To increase the efficiency of the opto-electrical properties, some functional groups can be introduced in coordination compounds. − Improving the light absorption is paramount for the usage of sunlight because over 95% solar energy is in the visible and the near-infrared regions. ,, In order to design photothermal molecules with the full light spectrum absorption for achieving better light-harvesting, several optical absorption centers can be introduced by the IVCT process. Based on the previous progress, the light absorption ability will be further enhanced both in the visible and the near-infrared range with the higher content of Cu II atoms .…”

The first mixed-valence nanocluster Cu I /Cu II with the highest percentage of Cu II ions was synthesized by using 4-tert-butylcalix[4]arene (Calix4), with the formula DMF 2 ⊂[(CO 3 ) 2-@Cu II 6 Cu I 3 (Calix4) 3 Cl 2 (DMF) 5 (H 3 O)]•DMF (1), as a photothermal nanocluster. Its structure was characterized using single-crystal X-ray diffraction, Fouriertransform infrared spectroscopy, and powder X-ray diffraction. In addition, the charge state and chemical composition of the nanocluster were determined using electrospray ionization spectrometry and X-ray photoelectron spectroscopy (XPS) spectrum. The results of the XPS and X-ray crystallography revealed that there are two independent Cu II and Cu I centers in nanocluster 1 with the relative abundances of 66.6 and 33.3% for Cu II and Cu I , respectively. The nanocluster contains three four-coordinated Cu I ions with a square-planar geometry and six five-coordinated Cu II ions with a square pyramid geometry. The nanocluster shows strong nearinfrared optical absorption in the solid state and excellent photothermal conversion ability (the equilibrium temperature ∼78.2 °C) with the light absorption centers in 286−917 nm over previous reported pentanucleus Cu I 4 Cu II clusters and Cu II compounds.
