Polymorphic Structures of Monolayer J-Aggregates of Two Monomethine Cyanine Dyes at the Meso- and Nanoscale
The structures of J-aggregates of two monomethine dyes are compared at the meso- and nanoscale by using fluorescence and atomic force microscopy. The J-aggregates of the two dyes are found to have solely a monola...

Polymer Composite with J-Aggregates of Polymethine Dye as a Charge-Transport Layer of Organic Light-Emitting Diode
The effect of addition of J-aggregates of polymethine dye into the hole-transport layer of an organic light-emitting diode (OLED) on its characteristics and operational stability was studied. Water-soluble PEDOT:...

Polymorphic Single-Layer and Fibrillar Nanostructures of J-Aggregates of a Carbocyanine Dye
Abstract—J-aggregates of a carbocyanine dye (pyridinium salt of 3,3'-di-(γ-sulfopropyl)-4,5,4',5'-di(tieno-3'',2'')-9‑ethyl-tiatrimethine cyanine betaine) (CC) were studied via the high-resolution AFM method at t...

Molecular nanocrystals in polyaniline-based light-emitting diode structures
It is found that one of the types of molecular organic nanocrystals, the so-called J-aggregates, is able to modify optoelectronic properties of electroactive polymers. It is intrinsic that the polyaniline interpo...
