Trapping in dendrimers and regular hyperbranched polymers

, 2012
Dendrimers and regular hyperbranched polymers are two classic families of macromolecules, which can be modeled by Cayley trees and Vicsek fractals, respectively.

Theory of directed transportation of electronic excitation between single molecules through photonic coupling [PDF]

, 2008
The primary result of UV-Visible photon absorption by complex organic molecules is the population of short-lived electronic excited states. Transportation of their excitation energy between single molecules, formally mediated by near-field interactions ...

Chain‐End Grafting of RAFT Polyelectrolyte Macroligands to Stabilize Near‐Infrared‐Emitting Gold Nanoclusters

Macromolecular Rapid Communications, EarlyView.
Surface‐functionalized gold nanoclusters (AuNCs) are synthesized in situ by chain‐end grafting of RAFT polyelectrolytes at room temperature directly in water. It leads to highly stable polymer‐AuNCs nanohybrids emitting near‐infrared photoluminescence with µs lifetimes. ABSTRACT With their photoluminescence properties, gold nanoclusters (AuNCs, d<2 nm)

Tuning catalytic activity and sensitivity in urease‐based thin film biosensors using conjugated polymers and eugenol/biseugenol

Polymer International, EarlyView.
Hybrid thin films of conjugated polymers and urease modified with eugenol derivatives show that polymer–biomolecule interactions enhance catalytic activity while distinctly modulating electrolyte–insulator–semiconductor sensor sensitivity. Abstract Thin films have emerged as promising platforms for biosensor development due to their versatility and ...

A new class of polyphenolic carbosilane dendrimers binds human serum albumin in a structure-dependent fashion

Scientific Reports
The use of dendrimers as drug and nucleic acid delivery systems requires knowledge of their interactions with objects on their way to the target. In the present work, we investigated the interaction of a new class of carbosilane dendrimers functionalized

Structure and thermodynamics of platelet dispersions

, 2008
Various properties of fluids consisting of platelike particles differ from the corresponding ones of fluids consisting of spherical particles because interactions between platelets depend on their mutual orientations. One of the main issues in this topic

Hydrogen Atom Transfer Induces Photodegradation in Carbonyl‐Based Multi‐Resonance TADF Emitters

Angewandte Chemie, Volume 138, Issue 19, 4 May 2026.
Boosting triplet harvesting in N/C═O MR‐TADF emitters unexpectedly induces rapid photodegradation under oxygen‐free conditions. Spectroscopic studies reveal that triplet excited states trigger hydrogen‐atom transfer from solvent to the carbonyl unit, driven by triplet energetics and hydrogen electrophilicity.
