Summary
Charge transport in graphitic carbon nitrides occurs through diffusive hopping of polarons, showing high mobility. Transport is primarily perpendicular to polymer sheets, similar to 2D materials.
Area of Science:
- Materials Science
- Condensed Matter Physics
- Organic Electronics
Background:
- Polymeric graphitic carbon nitrides (CNs) are emerging materials with potential applications in electronics.
- Understanding charge transport mechanisms is crucial for optimizing their performance.
Purpose of the Study:
- To investigate the charge transport dynamics in polymeric graphitic carbon nitrides.
- To determine the mobility and directionality of charge carriers.
Main Methods:
- Analysis of ultrafast luminescence decay.
- Power-law fitting to determine transport characteristics.
Main Results:
- Charge transport is dominated by diffusive hopping of electron and hole polarons.
- Mobilities exceeding 10(-5) cm(2) V(-1) s(-1) were observed.
- Predominant charge transport direction is perpendicular to the graphitic polymer sheets.
Conclusions:
- Polymeric graphitic carbon nitrides exhibit efficient charge transport.
- The observed transport properties complement those of 2D materials like graphene.
- These findings suggest potential for polymeric CNs in advanced electronic devices.

Tetrahedral Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.

Different notations are used to represent the three-dimensional structure of molecules on two-dimensional surfaces. One of the most commonly used representations is the dash-wedge formula. The dashed wedges, solid wedges, and the plane lines indicate the groups situated behind the plane, coming out of the plane, and in the plane, respectively.

01:18Aromatic Hydrocarbon Cations: Structural Overview
4.3K
Cycloheptatriene is a neutral monocyclic unsaturated hydrocarbon that consists of an odd number of carbon atoms and an intervening sp3 carbon in the ring. The three double bonds in the ring correspond to 6 π electrons, which is a Huckel number, and therefore satisfies the criteria of 4n + 2 π electrons. However, the intervening sp3 carbon disrupts the continuous overlap of p orbitals. As a result, cycloheptatriene is not aromatic.

01:13Five-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,...
