Di Mauro A, Randazzo R, Spanò SF, Compagnini G, Gaeta M, D'Urso L, Paolesse R, Pomarico G, Di Natale C, Villari V, Micali N, Fragalà ME, D'Urso A, Purrello R.

Chem Commun (Camb). 2016 Nov 18;52(89):13094-13096. doi: 10.1039/c6cc05177d. Epub 2016 Aug 23.

Graphene oxide (GO) is one of the most appealing bidimensional materials able to interact non-covalently with achiral molecules and to act as chiral inducers. Vortexes can tune chirality and, consequently transfer a specific handedness to non-covalent host molecules, either...

Synthetic protocols for the nitration of corroles.

Journal of porphyrins and phthalocyanines

The modification of peripheral positions of corroles by introduction of nitro groups is an important functionalization of this macrocycle. The nitro substituent strongly influences the corrole behavior leading to the preparation of macrocycles with different properties, which can be...

Scientific teaching targeting faculty from diverse institutions.

Silicon complexes of corrole were obtained for the first time by reaction of the free-base corrole with hexachlorodisilane. The peripheral substituents of corrole strongly influence the nature of the reaction products: β-octaalkyl corrole was mainly isolated as the μ-oxo...

Excited-state dynamics and electronic structures of Al and Ga corrole complexes were studied as a function of the number of β-pyrrole iodine substituents. Using spectrally broad-band femtosecond-resolved fluorescence upconversion, we determined the kinetics of the Soret fluorescence decay, the...

Silver corrolates are attractive compounds from both practical and theoretical points of view. Indeed, they play a key role in peripheral functionalization reactions occurring at the macrocycle, enabling high-yield and regioselective group insertions useful to further elaborate the molecular...

Supramolecular Diblock Copolymers Featuring Well-defined Telechelic Building Blocks.

Angewandte Chemie (International ed. in English)

Elacqua E, Croom A, Manning KB, Pomarico SK, Lye D, Young L, Weck M.

Angew Chem Int Ed Engl. 2016 Dec 19;55(51):15873-15878. doi: 10.1002/anie.201609103. Epub 2016 Nov 17.

We report supramolecular AB diblock copolymers comprised of well-defined telechelic building blocks. Helical motifs, formed via reversible addition-fragmentation chain-transfer (RAFT) or anionic polymerization, are assembled with coil-forming and sheet-featuring blocks obtained via atom-transfer radical polymerization (ATRP) or ring-opening metathesis...

The reaction of 5,10,15-tris(4-tert-butylphenyl)corrole with 2,3-bis(bromomethyl)-5,6-dicyanopyrazine provides a new example of corrole ring expansion to a hemiporphycene derivative. The ring expansion is regioselective, with insertion of the pyrazine derivative at the 5-position of the corrole ring, affording the corresponding...

Ultrafast interfacial electron transfer in sensitized solar cells has mostly been probed by visible-to-terahertz radiation, which is sensitive to the free carriers in the conduction band of the semiconductor substrate. Here, we demonstrate the use of deep-ultraviolet continuum pulses...

Holography relies on the interference between a known reference and a signal of interest to reconstruct both the amplitude and the phase of that signal. With electrons, the extension of holography to the ultrafast time domain remains a challenge,...
