Lighting up the appealing world of hybrid perovskites (15/02/2022)
The growing demand for new compounds with excellent optoelectronic properties has motivated a strong scientific interest in developing and tailoring novel perovskites. Their unique physical properties make perovskites promising and appealing candidates for technological applications such as solar cells, LEDs, lasers, photodetector devices, etc… Perovskites can be described by the general formula ABX3 (see picture), where:
  • A is a monovalent cation (e.g., Cs+, MA+, FA+,…, with MA= methylammonium, FA=formamidinium);
  • B is a divalent metal cation (e.g., Sn2+, Pb2+);
  • X is a halide anion (e.g., Cl, Br, or I).
In three articles published in 2021 (Dhanabalan et al., 2021; Cinquino et al., 2021; Polimeno et al., 2021), researchers from Italy and Switzerland used the macromolecular crystallography beamline X06DA-PXIII at the Swiss Light Source (Switzerland), as well as BL-5A at the Photon Factory (Japan) to characterize hybrid organic-inorganic perovskites, for which the A cation is organic and the packing consists of alternating layers of organic and inorganic corner-sharing BX6 octahedra layers. The great and fascinating potential of these hybrid materials relies on the large tunability of their optoelectronic properties:  e.g.,  by changing the kind of organic molecules or the thickness of the inorganic slabs (i.e., the number n of the inorganic layers in the slabs) strong differences in the wavelength of the emission occur. To suitably engineer the optoelectronic properties of hybrid organic-inorganic perovskites, synchrotron radiation was instrumental (1) to identify and improve new crystalline materials, (2) to characterize the crystal packing, to identify the structure-property relationships, and consequently, to reveal the amazing optoelectronic properties of those new compounds. Single crystals of perovskites can be laminar samples of a few micron thick (as for our cases of study) with imbricate structures, which prevent the successful characterization using conventional laboratory X-ray sources. Here, small crystals down to a few tens of microns, combined with synchrotron beam turned out essential for successful structure solution and refinement of those new hybrid perovskites. In Dhanabalan et al., 2021, the collaboration with the Instituto Italiano di Tecnologia (IIT) of Genova, Italy, lead to the structural characterization of the hybrid perovskite (N-MDDA)2PbBr4, whose organic cation is an amine, revealing the presence of H-bonds responsible of the distortion of the inorganic chains and allowing to estimate the distortion degree of the chains. The collaboration with the Institute NANOTEC of the CNR of Lecce, Italy, yielded the crystal structure of the following 2 perovskites: (1) a new 2D hybrid organic-inorganic perovskite F(C6H5(CH2)2NH3)2PbI4 (Polimeno et al., 2021) featuring unique optical birefringence, as well as (2) two new 2D hybrid organic-inorganic perovskites (Cinquino et al., 2021), with a number of inorganic layers n > 1. The study proved the efficiency of a new synthesis protocol applied for preparing the compounds (C12)2(MA)n-1PbnI3n+1 (where C12= C12H25NH3+),  and determining the degree of distortion of the inorganic layers.  These works highlight the benefit of synchrotron radiation to characterize challenging crystalline perovskites crystals and open the door to further exploring the amazing world of perovskites.

Erionite Killer (17/05/2024)
L’erionite è uno dei cancerogeni naturali più pericolosi per l’uomo. Nell’Anatolia centrale, in Turchia, gli abitanti di tre paesini (Karain, Tuzköy e Sarihidir) l’hanno utilizzata inconsapevolmente per costruire abitazioni e edifici, ignari del fatto che il tufo friabile (contenente erionite) che utilizzavano, nascondeva un potere mortale che causava il cancro. L’Istituto di Cristallografia del Cnr (Cnr-Ic), in collaborazione con l’Università di Modena e Reggio Emilia e il sincrotrone di Grenoble, ne ha studiato in dettaglio la struttura cristallina: un primo importante passo verso la costruzione di un modello di cancerogenicità.

Nanomateriali inesplorati per semiconduttori senza piombo (23/03/2022)
Messo a punto un metodo di sintesi chimica che consente di ottenere una classe inesplorata di nanomateriali semiconduttori, detti calcoalogenuri, conformi alla Direttiva UE sull’utilizzo di sostanze pericolose (RoHS). Molto stabili ed efficienti nell’assorbimento della luce solare, si candidano in alternativa ai semiconduttori contenenti piombo. Autori della scoperta i ricercatori dell’Istituto di nanotecnologia e dell’Istituto di cristallografia del Cnr, assieme ai colleghi dell’Università del Salento e dell’Istituto Italiano di Tecnologia. Il lavoro è pubblicato su Angewandte Chemie ed è oggetto di domanda di brevetto All’evolversi delle tecnologie fotovoltaiche e dell’optoelettronica emergente si affianca lo sviluppo di nuovi materiali di sintesi, anche su scala nanometrica. Tra questi, i nanocristalli colloidali di semiconduttori inorganici attirano considerevole interesse grazie alle loro proprietà ottiche ed elettriche e alla prospettiva di processi sintetici a basso costo. Un gruppo di ricercatori afferenti all’Istituto di nanotecnologia (Cnr-Nanotec) di Lecce e all’Istituto di cristallografia (Cnr-Ic) di Bari del Consiglio nazionale delle ricerche, assieme ai colleghi dell’Università del Salento e dell’Istituto Italiano di Tecnologia – IIT, ha elaborato un innovativo metodo di sintesi chimica che consente di ottenere una classe inesplorata di nanomateriali, detti calcoalogenuri di bismuto. Questi nanomateriali, conformi alla Direttiva Ue che pone restrizioni all’utilizzo di sostanze pericolose (RoHS), si sono rivelati molto stabili ed efficienti nell’assorbimento della luce solare. Ciò li candida a promettente alternativa ai semiconduttori contenenti piombo, largamente impiegati. I risultati della ricerca sono pubblicati su Angewandte Chemie ed oggetto di una domanda di brevetto. “Il nostro metodo di sintesi si è rivelato affidabile e versatile, consentendoci di esplorare la classe dei calcoalogenuri di bismuto e di prepararne nanocristalli puri”, spiega Danila Quarta di Cnr-Nanotec, autrice della ricerca. “I nanocristalli di calcoalogenuro di bismuto sono stati utilizzati per la formulazione di inchiostri fotoattivi, con i quali sono stati realizzati elettrodi capaci di convertire luce solare in corrente elettrica, aprendo così alla possibilità di fabbricare dispositivi fotovoltaici, fotoelettrochimici e optoelettronici in maniera semplice e relativamente economica. Abbiamo dato avvio a un filone di ricerca che apre ad opportunità nuove, tutte da esplorare. Il nostro obiettivo ultimo è di contribuire ad offrire una prospettiva nuova per la conversione dell’energia solare a basso impatto ambientale”. “Questo metodo ci ha inoltre permesso di ottenere una nuova fase cristallina, la cui struttura è stata determinata per la prima volta dal nostro gruppo di ricerca”, aggiunge Anna Moliterni di Cnr-Ic. “I risultati dello studio indicano che con ogni probabilità potremmo individuare una serie di nuovi materiali, ancora da scoprire” dichiara Liberato Manna, dell’Istituto Italiano di Tecnologia, coautore della ricerca.
