Journal ArticleDOI
Stabilization through p-dimethylaminobenzaldehyde of a new NLO-active phase of [E-4-(4-dimethylaminostyryl)-1-methylpyridinium] iodide: synthesis, structural characterization and theoretical investigation of its electronic properties
Francesca Nunzi,Simona Fantacci,Elena Cariati,Elisa Tordin,Nicola Casati,Piero Macchi,Piero Macchi +6 more
TL;DR: In this article, a new kind of aggregation for the [DAMS+] chromophore molecules was observed, together with the often encountered J-type aggregation, an unprecedented "fishbone" coupling was observed.
Journal ArticleDOI
High pressure modification of organic NLO materials: large conformational re-arrangement of 4-aminobenzophenone
Elena Marelli,Nicola Casati,Fabia Gozzo,Piero Macchi,Petra Simoncic,Petra Simoncic,Angelo Sironi +6 more
TL;DR: In this article, the high pressure behavior of 4-aminobenzophenone, an organic NLO chromophore, is investigated for the solid state form of the 4-AMO.
Journal ArticleDOI
Magnetic order and enhanced exchange in the quasi-one-dimensional molecule-based antiferromagnet Cu(NO3)2(pyz)3.

TL;DR: The quasi-one-dimensional molecule-based Heisenberg antiferromagnet Cu(NO3)2(pyz)3 has an intrachain coupling J = 13.7(1) K () and exhibits a state of long-range magnetic order below TN = 0.105( 1) K, demonstrating a high degree of isolation for the Cu chains.
Journal ArticleDOI
Improving the quality of diamond anvil cell data collected on an area detector by shading individual diamond overlaps
TL;DR: In this paper, a utility was developed that shades these reflections during the integration, enabling their elimination before the solution or refinement, avoiding the error propagation to other reflections caused by overlapping spots, through the profile fitting procedure of an integration run.
Book ChapterDOI
A Guided Tour Through Modern Charge Density Analysis
TL;DR: In this paper, a concise summary is provided on the basic aspects of charge density analysis and an overview of the charge density research and developments over the last 10 years, with a glimpse is given to the issues which are treated in more details in the remaining chapters of this book.
