Conjugated Copolymers That Shouldn't Be [PDF]

Angewandte Chemie International Edition, 2021
AbstractMultiple studies have explored using cage silsesquioxanes (SQs) as backbone elements in hybrid polymers motivated by their well‐defined structures and physical and mechanical properties. As part of this general exploration, we report unexpected photophysical properties of copolymers derived from divinyl double decker (DD) SQs, [vinyl(Me)Si(O0.5)

Dacarbazine-Loaded Targeted Polymeric Nanoparticles for Enhancing Malignant Melanoma Therapy

Frontiers in Bioengineering and Biotechnology, 2022
Dacarbazine (DTIC) dominates chemotherapy for malignant melanoma (MM). However, the hydrophobicity, photosensitivity, instability, and toxicity to normal cells of DTIC limit its efficacy in treating MM.

Discussion on “Aperiodic Copolymers” [PDF]

ACS Macro Letters, 2015
In a recent Viewpoint (ACS Macro Lett. 2014, 3, 1020), J.-F. Lutz brought to the community's attention the need for more informative nomenclature, especially with respect to macromolecules with prescribed but not repeating sequences of monomers. Lutz proposes the use of the term "aperiodic" for this situation.
