Ru(II) tris-diimine complexes are known to exhibit emission at around 630 nm as a result of 1MLCT photoexcitation. The emission is quenched in the presence of a suitable semiconductor solid due to electron injection from the excited state of a Ru(II) complex to the conduction band of the adjacent semiconductor. Here we investigated emission quenching behaviour of RuII{(4,4′-(CH3)2-bpy)2(4,4′-(CH2PO3H2)2-bpy)} (bpy = 2,2′-bipryridine) adsorbed on HCa2Nb3O10 solids having an ordered lamellar structure or a disordered nanostructure. Even though electron injection from the excited state of the Ru complex to the conduction band of nanostructured HCa2Nb3O10 is thermodynamically less favorable than that of layered HCa2Nb3O10, faster electron injection was observed using nanostructured HCa2Nb3O10. Experimental results highlighted that electron injection from the excited Ru complex takes place not only in the conduction band of HCa2Nb3O10 but also mid-gap states whose density is strongly dependent on both the morphological feature and the preparation method of HCa2Nb3O10.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
