Supramolecular Conjugated Block Copolymers
While the performance of polymer−polymer bulk heterojunction organic photovoltaics (OPVs) is poor compared with polymer−fullerene OPVs, reducing or eliminating micrometer-scale phase separation in all-polymer OPVs may dramatically improve performance. Herein, we demonstrate that 2-ureido-4[1H]-pyrimidinone (UPy) quadruple hydrogen bonding interactions can be used to prevent micrometer-scale pha...
متن کاملMicellization of block copolymers
This article deals with recent progress including the author’s work in the field of block copolymer self-assembly in solution and on solid surfaces. The synthesis methods for producing block copolymers with well-defined structures, molecular weights and composition are outlined with emphasis on ionic and controlled free radical polymerization techniques. A general overview of the preparation, c...
متن کاملAcrylonitrile Block and Graft Copolymers
This paper presents a review of the methods available for preparing block and graft copolymers in which one component is acrylonitrile. Methods using polymer ions and polymer radicals are considered together with a useful new technique based on reactions of nitrile groups with amide compounds of group IV transition metals. Because of its polarity and its unusual solubility properties, a polyacr...
متن کاملBlock copolymers in tomorrow's plastics.
In this era of portability and rapid technological advances, polymers are more than ever under pressure to be cheap and offer tailored property profiles. Often, the key lies in designing blends and alloys carefully structured at the appropriate scale (preferably less than a micrometre) from existing polymers. Block copolymers - two or more different polymer chains linked together - have long be...
متن کاملRandom hydrophilic-hydrophobic copolymers
We study a single statistical amphiphilic copolymer chain AB in a selective solvent (e.g. water). Two situations are considered. In the annealed case, hydrophilic (A) and hydrophobic (B) monomers are at local chemical equilibrium and both the fraction of A monomers and their location along the chain can vary, whereas in the quenched case (which is relevant to proteins), the chemical sequence al...
