ABAB Phthalocyanines: Scaffolds for Building Unprecedented Donor-π-Acceptor Chromophores.
Ettore Fazio,Javier Jaramillo-Garcia,María Medel,Maxence Urbani,Maxence Urbani,Maxence Urbani,Michael Grätzel,Mohammad K. Nazeerudin,Gema de la Torre,Tomás Torres,Tomás Torres +10 more
TL;DR: In this article, a unique donor-π-acceptor phthalocyanines have been synthesized through the asymmetric functionalization of an ABAB PHTHC, crosswise functionalized with two iodine atoms through Pd-catalyzed cross-coupling reactions with adequate electron-donor and electron acceptor moieties.
Journal ArticleDOI

Molecular Origin of the Asymmetric Photoluminescence Spectra of CsPbBr3 at Low Temperature.
TL;DR: In this paper, the authors investigated the molecular origin of the asymmetric low-temperature photoluminescence spectra of CsPbBr3 and concluded that the origin of this phenomenon lies in a local dipole moment (and the induced Stark effect) due to the preferential localization of ions in either of two off-center positions of the empty space between the surrounding PbBr6 octahedra.
