Types of Step-Growth Polymers: Polyesters01:20

Types of Step-Growth Polymers: Polyesters

2.3K
The introduction of polyesters has brought major development to the textile industry. The wrinkle-free behavior of polyester blends has eliminated the need for starching and ironing clothes.
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the...

Polymer Classification: Stereospecificity

2.6K
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...

Variables Affecting Phosphorescence and Fluorescence

585
Fluorescence and phosphorescence are essential phenomena in fields like analytical chemistry, biological imaging, and materials science, where they detect molecular properties and visualize cellular structures. Understanding the variables that influence these luminescent behaviors is crucial for maximizing accuracy and efficiency in their applications. These variables can broadly be grouped into chemical structure, solvent properties, and external conditions, each playing a distinct role in...

Polymer Classification: Crystallinity

3.1K
Unlike ionic or small covalent molecules, polymers do not form crystalline solids due to the diffusion limitations of their long-chain structures. However, polymers contain microscopic crystalline domains separated by amorphous domains.
Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...

Polymer Classification: Architecture01:14

Polymer Classification: Architecture

2.9K
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...

Free-Radical Chain Reaction and Polymerization of Alkenes02:35

Free-Radical Chain Reaction and Polymerization of Alkenes

8.1K
The conversion of alkenes to macromolecules called polymers is a reaction of high commercial importance. The structure of the polymer is defined by a repeating unit, while the terminal groups are considered insignificant. The average degree of polymerization represents the number of repeating units in the polymer molecule and is denoted by the subscript n.

Area of Science:

  • Polymer Chemistry
  • Materials Science
  • Optoelectronics

Background:

  • Single-molecule white-light emission (SMWLE) is desirable for applications but challenging to achieve with nonconjugated polymers.
  • Clusteroluminogens (CLgens) are nonconjugated luminescent polymers, but their SMWLE fabrication remains difficult.

Purpose of the Study:

  • To report the first linear nonconjugated polyesters exhibiting SMWLE.
  • To explore structure-property relationships for tunable clusteroluminescence (CL) in these polyesters.

Main Methods:

  • Synthesis of 24 nonconjugated aliphatic polyesters via copolymerization of epoxides and anhydrides.
  • Experimental and computational studies to analyze structural effects on CL efficiency and color.
  • Investigation of monomer structure variations (succinic, trans-MA, cis-MA, CA) and their impact on secondary structures and luminescence.

Main Results:

  • Achieved tunable CL colors and efficiency by adjusting polyester primary and secondary structures.
  • Demonstrated that side-chain length influences CL efficiency without altering wavelength.
  • Showed that monomer modification (e.g., to CA) induces secondary structure changes (helix to sheet) and red-shifts CL from 460 to 570 nm via enhanced through-space π-π interactions.
  • Obtained pure SMWLE with CIE coordinates (0.30, 0.32) using CA-based polyesters.

Conclusions:

  • Established a new strategy for fabricating SMWLE materials from nonconjugated polyesters.
  • Provided insights into the CL emission mechanism by correlating hierarchical structures with optical properties.
  • Highlighted the potential of CLgens for advanced optical applications through structural regulation.
