TL;DR: In this paper, a comparative study of the stability of polymer/fullerene bilayers using two common OPV polymer donors poly(3-hexylthiophene), P3HT, and poly[N-9′-heptadecanyl-2,7-carbazole-alt-5,5-(4′,7′-di-2-thienyl-2′,1′,3′-benzothiadiazole)], PCDTBT, and four fullerene acceptors phenyl-C61
Abstract: A consensus is emerging that mixed phases are present in bulk heterojunction organic photovoltaic (OPV) devices. Significant insights into the mixed phases have come from bilayer stability measurements, in which an initial sample consisting of material pure layers of donor and acceptor is thermally treated, resulting in swelling of one layer by the other. We present a comparative study of the stability of polymer/fullerene bilayers using two common OPV polymer donors poly(3-hexylthiophene), P3HT, and poly[N-9′-heptadecanyl-2,7-carbazole-alt-5,5-(4′,7′-di-2-thienyl-2′,1′,3′-benzothiadiazole)], PCDTBT, and four fullerene acceptors phenyl-C61-butyric acid methyl ester, phenyl-C71-butyric acid methyl ester, [60]PCBM bis-adduct, and indene C60 bis-adduct. Using in situ spectroscopic ellipsometry to characterize the quasi-steady state behavior of the films, we find that the polymer glass transition temperature (Tg) is critical to the bilayer stability, with no significant changes occurring below Tg of the high ...

TL;DR: In this article, the solid-state supramolecular complexation of fullerenes C60 and C70 as well as some derivatives of C60 was attained by the use of a mechanochemical high-speed vibration milling technique.
Abstract: The solid-state supramolecular complexation of fullerenes C60 and C70 as well as some derivatives of C60 was attained with γ-cyclodextrin by the use of a mechanochemical high-speed vibration milling technique. Similarly C60 and the fullerene dimer C120 were complexed with sulfocalix[8]arene. The complexes produced were found to be soluble in water, and their solubility was examined by UV-vis spectroscopy.

TL;DR: In this paper, an unbiased search for the lowest energy geometric structures of medium-sized silicon clusters SiN (27 ≤ N ≤ 39) using a genetic algorithm and nonorthogonal tight binding method, followed by a refining and biased search using basin-hopping method coupled with density functional theory.
Abstract: We have performed an unbiased search for the lowest-energy geometric structures of medium-sized silicon clusters SiN (27 ≤ N ≤ 39) using a genetic algorithm and nonorthogonal-tight-binding method, followed by a refining and biased search using basin-hopping method coupled with density-functional theory. We show that the carbon fullerene cages are most likely generic cage motifs (“magic cages”) to form low-lying stuffed-cage silicon clusters (beyond the size N > 27). An empirical rule that provides optimal “stuffing/cage” combinations for constructing low-energy endohedral silicon fullerenes is suggested, with a hope that it can provide guidance to future synthesis of “bucky” silicon.

TL;DR: In this article, the assembly of zeolite-A monolayers on glass was shown to occur by formation of a large number of propylamine−fullerene−propylamine covalent linkages between each crystal and the glass substrate.
Abstract: Glass plates tethered with 3-aminopropyl groups were prepared and fullerene (C60) was mounted onto the amine groups via NH insertion of the terminal amine moiety into one of the double bonds of fullerene. Cubic zeolite-A crystals covered with 3-aminopropyl groups on the external surface were independently prepared by treating the crystals with (3-aminopropyl)triethoxysilane. The zeolite-A crystals readily assembled in the form of monolayers on the fullerene-tethering glass substrates when they were allowed to contact in boiling toluene. The assembled zeolite-A monolayers remained intact even after sonication for 5 min in toluene. In contrast, the assembly of zeolite crystals does not occur if the tethering of either 3-aminopropyl or fullerene is omitted. Based on the two contrasting results, the monolayer assembly of zeolite crystals on glass is proposed to occur by formation of a large number of propylamine−fullerene−propylamine covalent linkages between each zeolite crystal and the glass substrate.
