AI Article Synopsis
- The study introduces a method for measuring spectrally resolved second-harmonic generation (SHG) efficiencies in a series of newly developed non-centrosymmetric coordination polymers (CPs).
- These CPs are made from a specific linker and cobalt(II) ions, featuring mixed geometric arrangements that affect their optical properties.
- The research highlights the ability to tune the SHG optical spectra based on the choice of anions, revealing connections between SHG and solid-state absorption spectra.
Article Abstract
Powder second-harmonic generation (SHG) efficiencies are usually measured at single wavelengths. In the present work, we provide a proof of concept of spectrally resolved powder SHG measured for a newly obtained series of three non-centrosymmetric coordination polymers (CPs). CPs are constructed from tetrahedral linker-tetraphenylmethane-based tetraphosphonate octaethyl ester and cobalt(II) ions of mixed, octahedral (Oh), and tetrahedral (Td), geometries and different sets of donors (CoO6 vs CoX3O). Isostructurality of the obtained materials allowed for the determination of anion-dependent tunability of SHG optical spectra and their relationship with solid-state absorption spectra.
