Synthesis of Discrete Oligomers by Sequential PET-RAFT Single-Unit Monomer Insertion.
Uniform synthetic polymers with precisely defined molar mass and monomer sequence (primary structure) have many potential high-value applications. However, a robust and versatile synthetic strategy for these materials remains one of the great challenges in polymer synthesis. Herein we describe proof-of-principle experiments for a modular strategy to produce discrete oligomers by a visible-light...
متن کاملOne pot synthesis of poly(3-hexylthiophene)-block-poly(hexadecyloxylallene) by sequential monomer addition.
A series of poly(3-hexylthiophene)-b-poly(hexadecyloxylallene) copolymers has been synthesized in one pot via sequential monomer addition by using Ni(dppp)Cl2 as a single catalyst. The copolymerization has been revealed to proceed by a controlled chain extension mechanism and the block copolymer can self-assemble into a well-defined supramolecular structure in solution and exhibit microphase se...
متن کاملSynthesis of sequence controlled acrylate oligomers via consecutive RAFT monomer additions.
An effective procedure to synthesize sequence controlled oligoacrylates with up to four monomer insertions via the RAFT technique is presented. Two different sets of oligomers with a preferred monomer order were synthesized. Recycling SEC allowed for facile and automated purification of the monodisperse sequence-controlled materials.
متن کاملMonomer adds to preformed structured oligomers of Abeta-peptides by a two-stage dock-lock mechanism.
Nonfibrillar soluble oligomers, which are intermediates in the transition from monomers to amyloid fibrils, may be the toxic species in Alzheimer's disease. To monitor the early events that direct assembly of amyloidogenic peptides we probe the dynamics of formation of (Abeta(16-22))(n) by adding a monomer to a preformed (Abeta(16-22))(n-1) (n = 4-6) oligomer in which the peptides are arranged ...
متن کاملSequential Competitive Facility Location Problem in a Discrete Planar Space
In this paper, there are two competitors in a planar market. The first competitor, called, the leader, opens new facilities. After that, the second competitor, the follower, reacts to the leader’s action and opens r new facilities. The leader and the follower have got some facilities in advance in this market. The optimal locations for leader and follower are chosen among predefined candida...
