White-emitting film of diblock copolymer micelles with perovskite nanocrystals

Autor: Kyunghyeon Lee, Joon Young Kim, Byeong-Hyeok Sohn

Publikováno v: RSC Advances. 12:6389-6395

Perovskite nanocrystals are synthesized in diblock copolymer micelles to improve their processability and stability. The copolymer micelle approach allows fluorescence from a stretchable or flexible substrate by coating processes, and stable emission

Atomically sharp heterojunctions in lateral two-dimensional heterostructures can provide the narrowest one-dimensional functionalities driven by unusual interfacial electronic states. For instance, the highly controlled growth of patchworks of graphe

Patch formation on diblock copolymer micelles confined in templates for inducing patch orientation and cyclic colloidal molecules

Autor: Jonghyuk Jeon, Heejung Kang, Kyunghyeon Lee, Byeong-Hyeok Sohn

Publikováno v: Journal of colloid and interface science. 616

Chemically or physically distinct patches can be induced on the micelles of amphiphilic block copolymers, which facilitate directional binding for the creation of hierarchical structures. Hence, control over the direction of patches on the micelles i

Fluorescence Resonance Energy Transfer within Diblock Copolymer Micelles in the Proximity of Metal Nanoparticles

Autor: Seong Il Yoo, Byeong-Hyeok Sohn, Ki-Se Kim, Jeong-Hee Kim

Publikováno v: Macromolecular Research. 27:905-910

Recently, it has been reported that localized surface plasmon resonance of metal nanoparticles (NPs) can engineer fluorescence resonance energy transfer (FRET) process. By placing metal NPs in the vicinity of donor-acceptor pairs of fluorophores, the

In situ conversion from crew-cut to hairy micelles by surface-initiated polymerization

Autor: Kyung Tae Kim, Byeong-Hyeok Sohn

Publikováno v: Journal of colloid and interface science. 603

Whether spherical micelles of block copolymers have short or long coronas is intrinsically determined by the molecular weight of the corona-forming block with respect to that of the core block before the micelles are assembled. Because of the inheren

Publikováno v: Journal of colloid and interface science. 600

Patchy micelles of diblock copolymers can be polymerized into a linear supracolloidal chain. We measure the persistence and contour lengths of supracolloidal chains coated on a solid substrate to evaluate their flexibility. Based on the analysis, the
