Electronic Absorption Spectroscopy
Absorption spectroscopy in the ultraviolet, visible and near-infrared (UV-VIS-NIR) wavelength ranges is one of the oldest and most often used characterization methods in coordination chemistry. This overview illustrates examples ranging from four-coordinate and six-coordinate complexes of d-block elements to modern lanthanide complexes.

Indirect measurement of infrared absorption spectrum through thermal emission of meta-cavity array [PDF]
Controlling thermal emission is essential for various infrared spectroscopy applications. Metasurfaces can be utilized to control multiple degrees of freedom of thermal emission, enabling the compact thermal emission materials and devices. Infrared spectroscopy such as FTIR (Fourier transform infrared spectroscopy), usually requires external infrared ...

Synthesis and properties of novel star-shaped oligofluorene conjugated systems with BODIPY cores
Star-shaped conjugated systems with varying oligofluorene arm length and substitution patterns of the central BODIPY core have been synthesised, leading to two families of compounds, T-B1–T-B4 and Y-B1–Y-B4, with T- and Y-shaped motifs, respectively ...
