Imaging of polymer implants during surgical implantations is challenging in that most materials lack sufficient X-ray contrast. Synthetic derivatization with iodine serves to increase the scattering contrast but results in distinct physicochemical pr

Gold nanoparticles functionalized with amphiphilic polybutadiene-poly(ethylene glycol) (PB-PEG) V-shaped arms formed stable Langmuir monolayers at the air-water and the air-solid interfaces. At these interfaces, the binary arms vertically segregated

Star polymers composed of equal numbers of poly(ethylene oxide) (PEO) and polystyrene (PS) arms with variable lengths and a large (up to 38 total) number of arms, PEO(n)PS(n), have been examined for their ability to form domain nanostructures at the

We report a novel mechanism of assembly of dendronized rod molecules into a dense supramolecular fluorescencent web featuring self-propelled mechanistic inward motion of star-shaped aggregates within a solution droplet. We suggest that such a motion

Nanofibrillar micellar structures formed by the amphiphilic hyperbranched molecules within a Langmuir monolayer were utilized as matter for silver nanoparticle formation from the ion-containing water subphase. We observed that silver nanoparticles we

We studied Langmuir and Langmuir–Blodgett monolayers from amphiphiles with traditional (carboxylic) and bulky functionalized (epoxy) terminal groups at the air–water and air–solid interfaces. We demonstrated that the molecules with a central az

The structural ordering of mesogenic-terminated carbosilane dendrimers within surface monolayers was studied. We have shown that despite their symmetrical spherical shape layering with average spacing close to 6 nm is observed for dendrimers with but

An amphiphilic heteroarm star polymer containing 12 alternating hydrophobic/hydrophilic arms of polystyrene (PS) and poly(acrylic acid) (PAA) connected to a well-defined rigid aromatic core was studied at the air-water and the air-solid interfaces. A

We report on the “core-first” synthesis of asymmetric three- and four-arm poly(ethylene oxide) (PEO)−polystyrene (PS) star polymers with functional terminal groups of a general formula PEOn-b-PSm with n = 0, 1, and 2 and n + m ≤ 4. The synthe
