Fully Oxidized and Mixed-Valent Polyoxomolybdates Structured by Bisphosphonates with Pendant Pyridine Groups: Synthesis, Structure and Photochromic Properties

open access: yesInorganics, 2015
Hybrid organic-inorganic polyoxometalates (POMs) were synthesized in water by the reaction of a MoVI precursor with bisphosphonate ligands functionalized by pyridine groups. The fully oxidized POM [(MoVI3O8)2(O)(O3PC(O)(C3H6NH2CH2C5H4NH)PO3)2]4− has been

From Molecular Complexes to Functional Frameworks: A Journey through Noncovalent Interactions in Coordination Assemblies and Organic Crystals

open access: yesThe Chemical Record, EarlyView.
Coordination chemistry offers a versatile platform where noncovalent interactions play a critical role in driving the formation of self‐assemblies and supramolecular structures. This account chronicles our research trajectory, guided by the fundamental investigations into the structures and properties of transition metal complexes, toward the ...

Nanoparticles (NPs) of WO3-x Compounds by Polyol Route with Enhanced Photochromic Properties

open access: yesNanomaterials, 2019
Tungsten trioxide (WO3) is well-known as one of the most promising chromogenic compounds. It has a drastic change of coloration induced from different external stimuli and so its applications are developed as gas sensors, electrochromic panels or ...

Production of oriented nitrogen-vacancy color centers in synthetic diamond

open access: yes, 2011
The negatively charged nitrogen-vacancy (NV-) center in diamond is an attractive candidate for applications that range from magnetometry to quantum information processing. Here we show that only a fraction of the nitrogen (typically < 0.5 %) incorporated

Theoretical calculations of an osmium molecular switch [PDF]

open access: yes, 2013
Indexación: Web of Science; Scielo.ABSTRACT We have investigated the molecular, electronic and optical properties of the [Os(tpy-py)2]2+ complex (tpy-py = 4'-(4-pyridyl)-2,2':6',2"-terpyridine) and its protonated derivative [Os(tpy-pyH)2]4+ through ...

Advances in organic UV filters for sunscreens over the past decade

open access: yesPhotochemistry and Photobiology, EarlyView.
Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...

In situ observation and mechanistic elucidation of metastable colored species in crystalline state photochromism of trans-biindenylidenedione [PDF]

open access: yes, 2010
A metastable colored species from the photochromic reaction of trans-biindenylidenedione, which only proceeds in the crystalline state, has been directly observed by in situ crystal structure analysis method.

Properties of implanted and CVD incorporated nitrogen-vacancy centers: preferential charge state and preferential orientation [PDF]

open access: yes, 2011
The combination of the long electron state spin coherence time and the optical coupling of the ground electronic states to an excited state manifold makes the nitrogen-vacancy (NV) center in diamond an attractive candidate for quantum information ...

Fast and Stable Photochromic Oxazines. [PDF]

open access: yesThe Journal of Organic Chemistry, 2005
We have designed and synthesized two photochromic compounds incorporating fused indoline and benzooxazine fragments. Variable-temperature 1H NMR spectroscopy demonstrates that their central [1,3]oxazine ring opens thermally with free energy barriers ranging from 14 to 19 kcal mol(-1).
