Hybridization of Atomic Orbitals I

Hybridization of Atomic Orbitals I

The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an isolated atom. When atoms are bound together in a molecule, the wave functions combine to produce new mathematical descriptions that have different shapes. This process of combining the wave functions for atomic orbitals is called hybridization and is mathematically accomplished by the linear combination of atomic orbitals. The new orbitals that...

Hydroboration-Oxidation of Alkenes

Hydroboration-Oxidation of Alkenes

In addition to the oxymercuration–demercuration method, which converts the alkenes to alcohols with Markovnikov orientation, a complementary hydroboration-oxidation method yields the anti-Markovnikov product. The hydroboration reaction, discovered in 1959 by H.C. Brown, involves the addition of a B–H bond of borane to an alkene giving an organoborane intermediate. The oxidation of this intermediate with basic hydrogen peroxide forms an alcohol.

Structure of Benzene: Molecular Orbital Model

Structure of Benzene: Molecular Orbital Model

According to the molecular orbital (MO) model, benzene has a planar structure with a regular hexagon of six sp2 hybridized carbons. As shown in Figure 1, each carbon is bonded to three other atoms with C–C–C and H–C–C bond angles of 120°. The C–H bond length is 109 pm, and the C–C bond length is 139 pm which is midway between the single bond length of sp3 hybridized carbons (154 pm) and sp2 hybridized carbons (133 pm).

Background:

Scalable synthesis of elemental 2D materials beyond graphene remains a significant challenge.
Borophenes, 2D allotropes of boron, offer unique electronic properties but are difficult to produce.

Purpose of the Study:

To develop a versatile chemical vapor deposition (CVD) method for synthesizing borophenes and their heterostructures.
To enable the scalable production of high-quality borophenes with large single-crystalline domains.

Main Methods:

Utilized diborane, derived from borazine byproducts, as the boron source in CVD.
Grew borophenes on single-crystal substrates like Ir(111) and Cu(111).
Synthesized borophene-hexagonal boron nitride (hBN) heterostructures, including lateral interfaces and vertical van der Waals structures.

Main Results:

Successfully synthesized metallic borophene polymorphs on Ir(111) and Cu(111).
Created atomically precise lateral borophene-hBN interfaces and vertical heterostructures.
Demonstrated that a single hBN overlayer effectively protects borophene from oxidation.
Achieved large, single-crystalline borophene domains at the micrometer scale.

Conclusions:

The developed CVD method provides a straightforward approach for scalable borophene synthesis.
This advancement facilitates the study of borophene's fundamental properties.
The synthesis of protected borophene opens avenues for its incorporation into electronic devices.
