The low molecular weight heteroditopic monomer 1 forms supramolecular polymers in polar solution as shown, for example, by infrared laser-based dynamic light scattering (DLS), small-angle neutron scattering (SANS), electron microscopy (TEM, cryo-TEM)

In this study, electrostatic self-assembly of different polystyrene sulfonates and a set of tetravalent cationic porphyrins is investigated. It is shown that association of linear polystyrene sulfonates of different molar masses yields finite size na

Cylindrical poly(styrene sulfonate) brushes were combined with a tetravalent double-DABCO based counterion. With increasing addition of counterion, hydrodynamic radius and radius of gyration decrease and AFMreveals a conformation change from wormlike

We report on the electrostatic self-assembly of negatively charged cylindrical polystyrenesulfonate (NaPSS) brushes and stiff organic counterions of different valency. In particular, the tetravalent cationic porphyrin meso-tetrakis(4-(trimethylammoni

Cylindrical polymer brushes from PSSE and PSSD have been synthesized by a 'grafting from' approach by ATRP in solution. Starting from macroinitiators with 570 and 1600 repeat units, and 10-100% reactive site density, PSSD brushes with 10-40% grafting

In this study, we present a novel, multifaceted pH-triggerable system of self-organized hierarchical nanostructures. The system consists of meso-tetrakis(4-sulfonatophenyl)porphyrin (TPPS) and poly(2-vinylpyridine) cylindrical brushes (PVP brushes) a
