Polymers

Polymers

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...

Routes of Persuasion

Routes of Persuasion

Persuasion is the process of changing our attitude toward something based on some kind of communication. Much of the persuasion we experience comes from outside forces. How do people convince others to change their attitudes, beliefs, and behaviors? What communications do you receive that attempt to persuade you to change your attitudes, beliefs, and behaviors?

Nomenclature of Aryl and Heterocyclic Amines

Nomenclature of Aryl and Heterocyclic Amines

The simplest aromatic amine is phenylamine, which contains an –NH2 functionality directly attached to an aromatic ring. The name aniline is designated for this skeleton. As shown in Figure 1, the common names of the functionalized anilines involve prefixes ortho-, meta-, and para- to indicate the substitution position. Different functionalized aniline derivatives also have notable trivial names.

Conjugated Proteins

Conjugated Proteins

Simple proteins and protein complexes contain only amino acids. In contrast, many other proteins, called conjugated proteins, covalently bond with non-protein moieties.
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...

Materials Science

Background:

Polythiophenes are crucial in organic electronics.
Tuning side chains is key to controlling polymer properties.
Developing new synthetic routes for functional polythiophenes is ongoing.

Purpose of the Study:

To synthesize novel polythiophenes using ipso-arylative ring-opening polymerization.
To investigate the influence of specific aryl ketone side chains on polymer properties.
To evaluate the potential of these polymers as n-type organic semiconductors.

Main Methods:

Ipso-arylative ring-opening polymerization of functionalized indeno[2,1-b]thiophene monomers.
Characterization of polymer molecular weight (M_n) and properties.
Measurement of frontier orbital energy levels (HOMO/LUMO) and charge carrier mobilities.
Density functional theory (DFT) calculations.

Main Results:

Polymers with M_n up to 9 kg/mol were synthesized.
Pendant aroylphenyl side chains were successfully incorporated.
Poly(3-(2-(4-hexylbenzoyl)phenyl)thiophene) showed lower HOMO/LUMO levels (-5.9/-4.0 eV) than poly(3-hexylthiophene).
Significantly higher electron mobility (2×10^-3 cm²/Vs) than hole mobility (8×10^-6 cm²/Vs) was observed.
DFT calculations indicated backbone distortion influences charge mobility.

Conclusions:

The synthesized polythiophenes possess tunable electronic properties due to side-chain engineering.
The observed high electron mobility suggests suitability for n-type organic semiconductor applications.
Side-chain steric effects on backbone conformation are critical for charge transport.
