Scandium complexes with β-diketonate ligands are valuable precursors for the metal–organic chemical vapor deposition (MOCVD) of scandia based materials, but data on their volatilization thermodynamics crucial to MOCVD technology in a huge disarray. We have addressed this issue diagnostic tool principles group additivity and structure–property relationships, which had been developed by us specif...

A field-induced chiral YbIII Single-Molecule Magnet (SMM) displayed an unprecedented near-infrared circularly polarized luminescence (NIR-CPL) in the solid-state. The bridging bis(1,10-phenantro[5,6b])tetrathiafulvalene triad (L) allowed efficient sensitization of NIR 2F5/2→2F7/2 emission while NIR-CPL is associated to f-f transitions ion bearing β-diketonate derived-camphorate ancillary ligands.

The title compound, [Ni(C(5)HF(6)O(2))(2)(C(12)H(9)BrN(2))], the Ni(II) atom exhibits a pseudo-octa-hedral coordination geometry. The structure packs through C-H⋯Br inter-actions, forming a hydrogen-bonded ladder. There are also strong hydrogen-bonding inter-actions between two of the O atoms of the β-diketonate ligands and two H atoms on the pyridine ring of the Schiff base ligand.

In the title compound, [Gd(C(15)H(11)O(2))(3)(C(17)H(18)N(2))], the Gd(III) atom is coordinated by six O atoms from three β-diketonate ligands and two N atoms from a chiral ligand L(S),(S)-(+)-7,7-dimethyl-3-(2-pyrid-yl)-5,6,7,8-tetra-hydro-6,8-methano-iso-quinoline, in a coordination geometry best described as distorted square-anti-prismatic.

The continuous decrease on the geometric size of electronic devices and integrated circuits generates higher local power densities and localized heating problems that cannot be characterized by conventional thermographic techniques. Here, a self-referencing intensity-based molecular thermometer involving a di-ureasil organic-inorganic hybrid thin film co-doped with Eu(3+) and Tb(3+) tris (β-dik...

We have developed a ratiometric time-gated luminescence sensory system for in vivo imaging of hypochlorous acid (HClO) by preparing a dual-emissive nanoarchitecture of europiumand terbiumcomplex-modified silica nanoparticles. The design of this nanoarchitecture is based on our new finding that the strong, long-lived luminescence of the b-diketonate–Eu complex can be rapidly and selectively quen...
