Photocontrolled On-Surface Pseudorotaxane Formation with Well-Ordered Macrocycle Multilayers.

2016

The photoinduced pseudorotaxane formation between a photoresponsive axle and a tetralactam macrocycle was investigated in solution and on glass surfaces with immobilized multilayers of macrocycles. In the course of this reaction, a novel photoswitchable binding station with azobenzene as the photoswitchable unit and diketopiperazine as the binding station was synthesized and studied by NMR and UV/Vis spectroscopy. Glass surfaces have been functionalized with pyridine-terminated SAMs and subsequently with multilayers of macrocycles through layer-by-layer self assembly. A preferred orientation of the macrocycles could be confirmed by NEXAFS spectroscopy. The photocontrolled deposition of the …

On the Structure and Chiral Aggregation of Liquid Crystalline Star‐Shaped Triazines H‐Bonded to Benzoic Acids

2020

The ability of a star-shaped tris(triazolyl)triazine derivative to hierarchically build supramolecular chiral columnar organizations through the formation of H-bonded complexes with benzoic acids was studied from a theoretical and experimental point of view. The combined study has been done at three different levels including the study of the structure of the triazine core, the association with benzoic acids in stoichiometry 1:3, and the assembly of 1:3 complexes in helical aggregates. Although the star-shaped triazine core crystallizes in a non-C3 conformation, the C3 -symmetric conformation is theoretically predicted to be more stable and gives rise to a favorable C3 supramolecular 1:3 co…

Self-assembled dimers with supramolecular chirality

2003

The possibilities to form dimeric capsules with supramolecular chirality from tetraurea calix[4]arenes composed of two different phenolic urea units are discussed in general and demonstrated experimentally for various selected examples.

Supramolecular polymer chemistry meets computational chemistry: theoretical simulations on advanced self-assembling chiral materials

2018

AbstractComputational chemistry has gained an important role as a key tool to help rationalize the self-assembly of organic building blocks decorated with supramolecular recognition motifs. The adv...

New Quadratic Self-Assembly of Double-Decker Phthalocyanine on Gold(111) Surface : From Macroscopic to Microscopic Scale

2018

Unveiling the self-organization mechanism of semiconducting organic molecules onto metallic surfaces is the first step to design hybrid devices in which the self-assembling is exploited to tailor magnetic properties. In this study, double-decker rare-earth phthalocyanines, namely, lutetium phthalocyanine (LuPc2), are deposited on Au(111) gold surface forming large-scale self-assemblies. Global and local experimental techniques, namely, grazing incidence X-ray diffraction and scanning tunneling microscopy, supplemented by density functional theory calculations with van der Waals corrections, give insight into the molecular structural arrangement of the thin film and the self organization at …

Sulla legittimazione dell’amministratore di s.p.a. revocato ad impugnare la deliberazione assembleare di revoca

2013

Prendendo le mosse dal provvedimento reso dal tribunale di Palermo, il presente commento procede ad una ricostruzione del dibattito circa la legittimazione dell’amministratore revocato di s.p.a. ad impugnare la stessa deliberazione assembleare di revoca. Rilievo centrale assumono, da un canto, la ricognizione degli interessi tutelati dal meccanismo delle impugnazioni di cui agli artt. 2377 ss. c.c.; e, dall’altro, l’interpretazione di tali disposizioni da parte del tribunale, in ordine alla legittimazione attiva ad impugnare, riconosciuta dal decidente anche all’amministratore revocato. Particolare importanza assume, inoltre, il processo di valutazione comparativa, ex art. 2378, quarto comm…

Thermal and hydrothermal ageing of bio-based composite/metal hybrid materials. Application to the development of ultra-light and durable street furni…

2021

In the perspectives of the future city, the progressive use of autonomous vehicles seems to become unavoidable. The preparation of an adequate framework for the deployment of this future mobility represents an important issue. This requires revisiting the urban infrastructures of cities from the choice of material to the design, and to propose solutions based on mobile street furniture. Faced with this challenge, hybrid materials such fibre metal laminates (FML) present interesting characteristics. FML made of plant fibre composites are of particular interest to minimize their environmental impact. Thus, the objective of this thesis is to design and manufacture plant-fibre metal laminates a…

THE HUMAN RIGHT TO HEALTH: A RETROSPECTIVE ANALYSIS AFTER 70 YEARS OF INTERNATIONAL RECOGNITION

2018

In 1948, the General Assembly of the United Nations adopted the first international text recognising universal human rights for all; the Universal Declaration of Human Rights. Article 25 recognises the right to an adequate standard of living, which includes the right to health and medical care. On the occasion of the 70th anniversary of the Declaration, this article presents an overview of the main developments that have been made towards understanding the content and implications of the right to health, as well as an analysis of some specific advancements that aim to facilitate the enforcement thereof. These include: a) the implication of private entities as responsible for right to health…
