Des films de puits quantiques organiques-inorganiques à base de pérovskite de bromure de plomb incorporant des chromophores aromatiques polycycliques dans la couche organique (en d'autres termes, des puits quantiques hybrides combinant un semi-conducteur au bromure de plomb et des semi-conducteurs organiques) ont été préparés en utilisant la technique de revêtement par rotation du DMF. solution dans laquelle PbBr2 et les bromures d'alkylammonium qui étaient liés aux aromatiques polycycliques, au pyrène, au phénanthrène et à l'anthracène. Lorsque le bromure de méthylammonium lié au pyrène, qui présente une section transversale moléculaire relativement petite par rapport au plan semi-conducteur inorganique, a été utilisé, une structure pérovskite à base de bromure de plomb a été formée avec succès dans les films revêtus par centrifugation. Lorsque les bromures d'ammonium liés au phénanthrène et à l'anthracène, dont les chromophores ont de grandes sections efficaces moléculaires, ont été utilisés, les structures pérovskites à base de bromure de plomb ne se sont pas formées. Cependant, l’introduction de chaînes alkyles plus longues dans les bromures d’ammonium liés aux aromatiques a permis de former la structure pérovskite.

Abstract: Lead bromide-based perovskite organic-inorganic quantum-well films incorporated polycyclic aromatic chromophores into the organic layer (in other words, hybrid quantum-wells combined lead bromide semiconductor and organic semiconductors) were prepared by use of the spin-coating technique from the DMF solution in which PbBr2 and alkyl ammonium bromides which were linked polycyclic aromatics, pyrene, phenanthrene, and anthracene. When the pyrene-linked methyl ammonium bromide, which has a relatively small molecular cross-section with regard to the inorganic semiconductor plane, was employed, a lead bromide-based perovskite structure was successfully formed in the spin-coated films. When the phenanthrene-linked and anthracene-linked ammonium bromides, whose chromophore have large molecular cross-sections, were employed, lead bromide-based perovskite structures were not formed. However, the introduction of longer alkyl chains into the aromatics-linked ammonium bromides made it possible to form the perovskite structure.
