Interfacial micellar structures from novel amphiphilic star polymers.
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. At the air-water interface, the molecules spontaneously form pancakelike micellar aggregates which measure up to several microns in diameter and 5 n...
متن کاملConjugated Polymers as Fluorescence-based Chemical Sensors
Reported by Jay Wackerly November 1, 2004 INTRODUCTION A chemical sensor is a molecule that interacts with another molecule giving a measurable signal in response. Chemical sensors based on conjugated polymers have received a great deal of attention due to their ability to detect analytes at low concentrations. Fluorescence quenching provides an effective means for detection because of the extr...
متن کاملPiezochromic fluorescence in liquid crystalline conjugated polymers.
Liquid crystalline diphenylacetylene polymer derivatives showed piezochromic fluorescence via order-to-disorder phase transition.
متن کاملFacile Interfacial Electron Transfer of Hemoglobin Mediated by Conjugated Polymers
We herein describe a method of depositing hemoglobin (Hb) and sulfonated polyaniline (SPAN) on GC electrodes that facilitate interfacial protein electron transfer. Well-defined, reproducible, chemically reversible peaks of Hb and SPAN can be obtained in our experiments. We also observed enhanced peroxidase activity of Hb in SPAN films. These results clearly showed that SPAN worked as molecular ...
متن کاملRigid hydrophilic structures for improved properties of conjugated polymers and nitrotyrosine sensing in water.
The efficient synthesis of a hydrophilic monomer bearing a three-dimensional noncompliant array of hydroxyl groups is described that prevents water-driven excimer features of hydrophobic poly(p-phenylene ethynylene) backbones. Sensitivity of the polymer to 3-nitrotyrosine is also discussed.
