Photophysical Properties of Eu3+ β-Diketonates with Extended π-Conjugation in the Aromatic Moiety

Synthesis and photophysical properties of extended π conjugated naphthalimides.

A series of π conjugated naphthalimide derivatives having an imide group as an acceptor conjugated with a methoxy arylethynyl or a methoxyphenyl triazole as a donor were prepared by Sonogashira coupling or "click" chemistry. Their photophysical properties were investigated by steady state and time resolved fluorescence spectroscopy and modelled by TD-DFT calculations. Compound Naphth-AlkyneOMe ...

The effect of π-conjugation in the macrocyclic ring on the photophysical properties of a series of thiaaceneporphyrinoids.

In a series of thiaaceneporphyrinoids, their conformers exhibit macrocyclic π-conjugation pathways controlled by a dihedral angle between the porphyrin framework and acene planes. Conformational equilibria significantly affect the photophysical properties of these macrocycles.

Photophysical Properties of Aromatic and Antiaromatic Porphyrinoids

Theoretical research on the effect of regulated π-conjugation on the photophysical properties of Ir(III) complexes.

In this work, the effect of regulated host and auxiliary ligand π-conjugation on the photophysical properties of a series of Ir(III) carbene complexes is examined by using the start-of-the-art theoretical methods. According to our results, all of the lowest-lying and strongest absorption peaks can be assigned as having a mixed ligand-to-ligand/metal-to-ligand charge transfer (LLCT/MLCT) charact...
