Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 123784-07-6, is researched, Molecular C9H6BrNS, about Photophysics of Organometallic Platinum(II) Derivatives of the Diketopyrrolopyrrole Chromophore, the main research direction is organometallic platinum diketopyrrolopyrrole chromophore.Related Products of 123784-07-6.
A pair of diketopyrrolopyrrole (DPP) chromophores that are end-functionalized with platinum containing “”auxochromes”” were subjected to electrochem. and photophys. study. The chromophores contain either platinum acetylide or ortho-metalated 2-thienylpyridinyl(platinum) end-groups (DPP-Pt(CC) and DPP-Pt(acac), resp.). The ground state redox potentials of the chromophores were determined by solution electrochem., and the HOMO and LUMO levels were estimated The chromophores’ photophys. properties were characterized by absorption, photoluminescence, and time-resolved absorption spectroscopy on time scales from sub-picoseconds to microseconds. D. functional theory (DFT) computations were performed to understand the MOs involved in both the singlet and triplet excited state photophysics. The results reveal that in both platinum DPP derivatives the organometallic auxochromes have a significant effect on the chromophores’ photophysics. The most profound effect is a reduction in the fluorescence yields accompanied by enhanced triplet yields due to spin-orbit coupling induced by the metal centers. The effects are most pronounced in DPP-Pt(acac), indicating that the orthometalated platinum auxochrome is able to induce spin-orbital coupling to a greater extent compared to the platinum acetylide units.
