Summary
Supramolecular polymers were formed using ureidopyrimidinone functionalized pillar[5]arene (UPyP5) and a bisparaquat derivative (G). Orthogonal binding interactions, including hydrogen bonding and host-guest chemistry, are key to creating these linear assemblies.
Area of Science:
- Supramolecular chemistry
- Polymer science
Background:
- Pillar[5]arenes are macrocyclic hosts with tunable recognition properties.
- Supramolecular polymers offer dynamic and responsive material characteristics.
Purpose of the Study:
- To synthesize ureidopyrimidinone functionalized pillar[5]arene (UPyP5).
- To investigate the formation of supramolecular polymers using UPyP5 and a bisparaquat derivative (G).
- To elucidate the role of orthogonal binding interactions in assembly formation.
Main Methods:
- Synthesis of UPyP5.
- Complexation studies between UPyP5 and bisparaquat derivative (G).
- Characterization of the resulting supramolecular assembly.
Main Results:
- UPyP5 successfully complexed with the bisparaquat derivative (G).
- Formation of supramolecular polymers was achieved at relatively high concentrations.
- Evidence suggests orthogonal binding interactions are crucial for linear assembly.
Conclusions:
- Ureidopyrimidinone functionalized pillar[5]arene is an effective building block for supramolecular polymers.
- Quadruple hydrogen bonding and host-guest interactions cooperatively drive the formation of linear supramolecular assemblies.

01:14Polymer Classification: Architecture
Polymers are classified as linear or branched on the basis of their chain architecture. The polymer chains in linear polymers have a long chain-like structure with minimal to no branching at all. Even if a polymer features large substituent groups on the monomer, which appear as branches to the skeleton, it is not considered a branched polymer. A branched polymer contains secondary polymer chains that arise from the main polymer chain. The branching occurs when the polymer growth shifts from...
01:24Characteristics and Nomenclature of Copolymers
Copolymers are the products obtained from the polymerization of multiple monomer species. So, in a polymer chain itself, there can be multiple repeating units that come from different monomers. The process of synthesizing a polymer from different monomer species is called copolymerization. When two monomers are involved, the polymer is known as a bipolymer. Polymers with three and four monomers are termed terpolymers and quaterpolymers, respectively. Figure 1 depicts the copolymerization of...
01:20Anionic Chain-Growth Polymerization: Overview
The polymerization process that involves carbanion as an intermediate is called anionic polymerization. It is also a type of addition or chain-growth polymerization. Anionic polymerization gets initiated by a strong nucleophile such as an organolithium or a Grignard reagent. The most commonly used initiator for anionic polymerization is butyl lithium. Monomers involved in anionic polymerization must possess a vinyl group bonded to one or two electron-withdrawing groups. For instance,...
02:34Polymers
The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the properties that they exhibit. Additionally,...
01:04Anionic Chain-Growth Polymerization: Mechanism
The mechanism for anionic chain-growth polymerization involves initiation, propagation, and termination steps. In the initiation step, a nucleophilic anion, such as butyl lithium, initiates the polymerization process by attacking the π bond of the vinylic monomer. As a result, a carbanion, stabilized by the electron‐withdrawing group, is generated. The resulting carbanion acts as a Michael donor in the propagation step and attacks the second vinylic monomer, which acts as a Michael acceptor.
01:26Polymer Classification: Stereospecificity
Polymerization generates chiral centers along the entire backbone of a polymer chain. Accordingly, the stereochemistry of the substituent group has a significant effect on polymer properties. Polymers formed from monosubstituted alkene monomers feature chiral carbons at every alternate position in the polymer backbone. Relative to the predominant orientation of substituents at the adjacent chiral carbons, the polymer can exist in three different configurations: isotactic, syndiotactic, and...
