The photophysical and ion-sensing properties of densely grafted conjugated polymer poly-p-phenylenevinyleneg-poly(2-(methacryloyloxy)ethyl)trimethylammonium chloride (PPV-g-PMETAC) are presented herein. The grafted polymer exhibits excellent iodide-sensing which is easily observed using fluorescence spectroscopy. The iodide detection limit for PPV-g-PMETAC was found to be 10 nM and was independent of temperature and pH <12. The change in fluorescence of PPV-g-PMETAC, upon exposure to iodide, was attributed to polymer aggregation due to changes in the morphology of the grafted PMETAC side chains, which was observed using atomic force microscopic and dynamic light scattering studies.

“…For instance, photoluminescence generally improves with increasing side chain length as the sterically repulsive side chains prevent the conjugated backbones from aggregating and thereby minimises the quenching processes. 16,[22][23][24] On the other hand, the presence of insulating polymeric side chains can dilute the conjugated segments from forming an effective conductive pathway when the graft copolymers are in their doped state, leading to loss of electrical conductivity. 14 For CP-based graft copolymer films, however, the electrochemical process and the thin film behaviour at different redox states have not been investigated as a function of side chain length to the best of our knowledge.…”

Electronic graft copolymers with conjugated polymer backbones are emerging as promising materials for various organic electronics. These materials combine the advantages of organic electronic materials, such as molecular tunability of opto-electronic and electrochemical properties, with solution processability and other 'designer' physical and mechanical properties imparted through the addition of grafted polymer side chains. Future development of such materials with complex molecular architecture requires a better understanding of the effect of molecular parameters, such as side chain length, on the structure and, in turn, on the electronic properties. In this study, poly(thiophene)-graft-poly(acrylate urethane) (PTh-g-PAU) was examined as a model system and we investigate the effect of side chain length on the overall shape and size in solution. Furthermore, the changes in the swelling behaviour of the graft copolymer thin films help in understanding their electrochemical redox properties.

“…For instance, side chain engineering of CPs has rendered the material's solubility to facilitate large‐area fabrication of organic devices and sensors through solution‐based processes . In addition to solubility, other features such as biomimetic functionalities, which include dry‐adhesion, stimuli‐responsiveness, sensing, mechanical stretchability, and self‐healing can be tailored and expressed through incorporation of polymeric side chains onto the CP, as demonstrated by us and others …”

Here, the synthesis of a novel poly(pyrrole phenylene) (PpyP) that is both modular in ways of functionalization and soluble in organic solvents is reported, and therefore solution processable. This is achieved through the functionalization of the side‐chain substituents in pyrrole phenylene (PyP) repeating units. t Butyl acrylate brushes are first grafted through atom transfer radical polymerization from one type of PyP, followed by oxidative chemical co‐polymerization of the grafted PyP with a PyP bearing different side chains—either an azide or a methoxy moiety, resulting in a soluble PpyP where solubility is not dopant‐dependent. Successful post‐polymerization modification through “click” chemistry and post‐polymerization processing via electrospinning are also demonstrated. Additionally, performed computational calculations indicate planarity of the novel polyrrole phenylene monomers and ionisation potentials that favor α–α bond formation during their polymerization.
