A new era of LMCT: leveraging ligand-to-metal charge transfer excited states for photochemical reactions.

Ligand-to-metal charge transfer (LMCT) excited states are capable of undergoing a wide array of photochemical reactions, yet receive minimal attention compared to other charge transfer excited states. This work provides general criteria for designing transition metal complexes that exhibit low energy LMCT excited states and routes to drive photochemistry from these excited states. General design principles regarding metal identity, oxidation state, geometry, and ligand sets are summarized.

Electronic Structure and Photophysics of Low Spin d Metallocenes.

The electronic structure and photophysics of two low spin metallocenes, decamethylmanganocene (MnCp*) and decamethylrhenocene (ReCp*), were investigated to probe their promise as photoredox reagents. Computational studies support the assignment of E ground state configurations and low energy ligand-to-metal charge transfer transitions for both complexes. Weak emission is observed at room temperature for ReCp* with τ = 1.

An Aluminum-Based Metal-Organic Cage for Cesium Capture.

Metal-organic cages are a class of supramolecular structures that often require the careful selection of organic linkers and metal nodes. Of this class, few examples of metal-organic cages exist where the nodes are composed of main group metals. Herein, we have prepared an aluminum-based metal-organic cage, H[Al(pdc)(OAc)O] (Al-pdc-AA), using inexpensive and commercially available materials.

Critiques, Ethics, Prestige and Status: A Survey of Editors in Economics.

This study examines survey data on the views of editors of economics journals on common critiques of the discipline, ethics and editorial practices, and the role of prestige and status in publishing. We utilize an ordered probit model to investigate whether editors or journal characteristics are systematically related to editors' views, controlling for gender and editorial position. Regression results show that editors from top-ranked journals are less likely to agree with common disciplinary critiques, more likely to support market solutions and less likely to agree with concerns about editorial practices.

A New Class of Metal-Cyclam-Based Zirconium Metal-Organic Frameworks for CO Adsorption and Chemical Fixation.

Metal-organic frameworks (MOFs) have shown great promise in catalysis, mainly due to their high content of active centers, large internal surface areas, tunable pore size, and versatile chemical functionalities. However, it is a challenge to rationally design and construct MOFs that can serve as highly stable and reusable heterogeneous catalysts. Here two new robust 3D porous metal-cyclam-based zirconium MOFs, denoted VPI-100 (Cu) and VPI-100 (Ni), have been prepared by a modulated synthetic strategy.
