The State School Mental Health Profile: Findings from 25 States.

Background: State-level leadership and conditions are instrumental to local and regional comprehensive school mental health system (CSMHS) quality, sustainability, and growth. However, systematic documentation of state-level school mental health (SMH) policy, infrastructure, funding, and practice is limited.

Methods: Using a multi-phase, multi-method process, we developed the State School Mental Health Profile (State Profile) to offer a comprehensive landscape of state SMH efforts.

Excited state processes of dinuclear Pt(II) complexes bridged by 8-hydroxyquinoline.

Dinuclear d Pt(II) complexes, where two mononuclear square planar Pt(II) units are bridged in an "A-frame" geometry, possess photophysical properties characterised by either metal-to-ligand-(MLCT) or metal-metal-ligand-to-ligand charge transfer (MMLCT) transitions determined by the distance between the two Pt(II) centres. When using 8-hydroxyquinoline (8HQH) as the bridging ligand to construct novel dinuclear complexes with general formula [C^NPt(μ-8HQ)], where C^N is either 2-phenylpyridine (1) or 7,8-benzoquinoline (2), triplet ligand-centered (LC) photophysics results echoing that in a mononuclear model chromophore, [Pt(8HQ)] (3). The lengthened Pt-Pt distances of 3.

Metal-Metal-to-Ligand Charge Transfer in Pt(II) Dimers Bridged by Pyridyl and Quinoline Thiols.

The investigation of two distinct species of square planar dinuclear Pt(II) dimers based on -[Pt(CN)(μ-NS)], where CN is either 2-phenylpyridine (ppy) or benzo()quinoline (bzq) and NS is pyridine-2-thiol (pyt), 6-methylpyridine-2-thiol (Mpyt), or 2-quinolinethiol (2QT), is presented. Each molecule was thoroughly characterized with electronic structure calculations, static UV-vis and photoluminescence (PL) spectroscopy, and cyclic voltammetry, along with transient absorbance and time-gated PL experiments. These visible absorbing chromophores feature metal-metal-to-ligand charge-transfer (MMLCT) excited states that originate from intramolecular d-d metal-metal σ-interactions and are manifested in the ground- and excited-state properties of these molecules.

Understanding the influence of geometric and electronic structure on the excited state dynamical and photoredox properties of perinone chromophores.

In this work, a series of eight similarly structured perinone chromophores were synthesized and photophysically characterized to elucidate the electronic and structural tunability of their excited state properties, including excited state redox potentials and fluorescence lifetimes/quantum yields. Despite their similar structure, these chromophores exhibited a broad range of visible absorption properties, quantum yields, and excited state lifetimes. In conjunction with static and time-resolved spectroscopies from the ultrafast to nanosecond time regimes, time-dependent computational modeling was used to correlate this behavior to the relationship between non-radiative decay and the energy-gap law.

Accessing the triplet manifold of naphthalene benzimidazole-phenanthroline in rhenium(I) bichromophores.

The steady-state and ultrafast to supra-nanosecond excited state dynamics of -[Re(NBI-phen)(CO)(L)](PF) (NBI-phen = 16H-benzo[4',5']isoquinolino[2',1':1,2]imidazo[4,5-][1,10]phenanthrolin-16-one) as well as their respective models of the general molecular formula [Re(phen)(CO)(L)](PF) (L = PPh and CHCN) has been investigated using transient absorption and time-gated photoluminescence spectroscopy. The NBI-phen containing molecules exhibited enhanced visible light absorption with respect to their models and a rapid formation (<6 ns) of the triplet ligand-centred (LC) excited state of the organic ligand, NBI-phen. These triplet states exhibit an extended excited state lifetime that enable the energized molecules to readily engage in triplet-triplet annihilation photochemistry.
