Field Effect Transistor01:29

Field Effect Transistor

1.8K
Field-effect transistors (FETs) are integral to electronic circuits and distinguished by their three-terminal setup: the gate, drain, and source. These transistors operate as unipolar devices, which utilize either electrons or holes as charge carriers, in contrast to bipolar transistors, which use both types of carriers. The primary function of the FET is to modulate the flow of these carriers from the source to the drain through a channel. The voltage difference between the gate and source...

Five-Membered Heterocyclic Aromatic Compounds: Overview01:13

Five-Membered Heterocyclic Aromatic Compounds: Overview

6.1K
Heterocyclic aromatic compounds are cyclic compounds that are aromatic and have one or more heteroatoms—atoms other than carbon, in the ring. Depending upon the number of atoms present in the ring, they can be either five or six-membered. Examples of five-membered heterocyclic aromatic compounds include pyrrole, furan, thiophene, and imidazole. Pyrrole consists of one nitrogen atom having one lone pair of electrons. Furan and thiophene have one oxygen and one sulfur heteroatom,...

Introduction
A comparison of the enthalpies of hydrogenation of dienes reveals that conjugated dienes release less heat on hydrogenation, rendering them more stable than their nonconjugated analogs.

π Electron Effects on Chemical Shift: Overview01:27

π Electron Effects on Chemical Shift: Overview

1.9K
An applied magnetic field causes loosely bound π-electrons in organic molecules to circulate, producing a local or induced diamagnetic field over a large spatial volume. As the molecules tumble in solution, the field generated by π-electrons in spherical substituents results in a zero net field. However, the net field generated by π-electrons in non-spherical substituents is not zero. The effect of this induced field depends on the orientation of the molecule with respect to B0,...

π Molecular Orbitals of 1,3-Butadiene01:24

π Molecular Orbitals of 1,3-Butadiene

12.9K
Conjugated dienes have lower heats of hydrogenation than cumulated and isolated dienes, making them more stable. The enhanced stabilization of conjugated systems can be understood from their π molecular orbitals.
The simplest conjugated diene is 1,3-butadiene: a four-carbon system where each carbon is sp2-hybridized and has an unhybridized p orbital that contains an unpaired electron. According to molecular orbital theory, atomic orbitals combine to form molecular orbitals such that the...

Background:

  • Resonance-assisted hydrogen bonds (RAHBs) are crucial for stabilizing molecular structures.
  • Thieno[3,2-b]thiophene and 2,2'-bithiophene cores are promising building blocks for organic electronic materials.

  • Fabrication and testing of OFET devices using TTPY and BTPY thin films.
  • Thin film microstructural characterization (e.g., XRD, SEM).

Main Results:

  • TTPY and BTPY exhibit stable, planar conformations due to moderate RAHBs along the long axis and weaker interactions along the short axis.
  • RAHBs provide significant enthalpic stabilization (>10 kcal mol⁻¹) and are entropically favorable, ensuring planarity at higher temperatures.
  • TTPY demonstrates closer π-π stacking and higher crystallinity compared to BTPY.
  • TTPY-based OFETs achieve a maximum hole mobility of 0.035 cm² V⁻¹ s⁻¹, outperforming BTPY-based devices (0.026 cm² V⁻¹ s⁻¹).

Conclusions:

  • RAHBs are effective in creating rigid, planar molecular architectures with enhanced thermal stability.
  • Molecular packing and crystallinity significantly influence charge transport properties in organic semiconductors.
  • TTPY represents a promising material for high-performance organic electronics due to its optimized structure and packing.
