Titanium (IV) acetylacetonate (Ti (ACAC) ?) is an organic metal complex, which is formed by the combination of titanium center and acetylacetone (ACAC) ligand. Because of its good solubility, stability and catalytic activity, it has important applications in many fields. The following are its main application directions:

1. catalytic field

Polymerization catalyst:

It is used to catalyze the synthesis of polyester (such as pet, PLLA) and promote transesterification or ring opening polymerization; It can also be used for the preparation of polycarbonate.

Oxidation reaction:

It is used as a catalyst in the epoxidation of olefins (such as the conversion of propylene to propylene oxide) or the oxidation of alcohols to ketones/aldehydes.

Photocatalysis:

As a photosensitizer or cocatalyst, it participates in the photolysis of water to produce hydrogen or the reduction of CO ɑ.

2. Materials Science

Titanium dioxide (TiO ɑ) precursor:

Nano TiO ɑ was prepared by sol-gel method or chemical vapor deposition (CVD) for photocatalysts, solar cells (such as dye-sensitized cells), antibacterial coatings, etc.

Functional coating:

As a precursor of high temperature resistant or corrosion resistant coatings (such as aviation materials or protective coatings for electronic components).

Organic inorganic hybrid materials:

It is used to prepare high-performance composites and enhance mechanical strength or thermal stability.

3. organic synthesis

Coupling reaction:

Promote the formation of C-C bond or C-O bond, such as Suzuki coupling or Heck reaction.

Asymmetric synthesis:

It combines with other chiral ligands to catalyze the synthesis of chiral molecules (such as pharmaceutical intermediates).

4. optoelectronic and electronic materials

Dielectric materials:

It is used to prepare thin films with high dielectric constant and applied to capacitors or semiconductor devices.

Electronic transport layer:

It can be used as electron transport material in organic light emitting diodes (OLEDs) or perovskite solar cells.

5. other applications

Crosslinking agent:

Enhance the crosslinking density in polymer materials and improve the heat resistance or mechanical properties.

Biomedicine:

As part of drug carrier or biological imaging reagent (further biocompatibility verification is required).

matters needing attention

Titanium acetylacetonate is sensitive to moisture and oxygen, and should be operated in an inert atmosphere. Its toxicity is low, but long-term exposure still needs to follow the laboratory safety specifications.

These applications reflect the versatility of titanium acetylacetonate in chemical synthesis, advanced materials and energy technology. The specific use needs to optimize the coordination environment and reaction parameters according to the reaction conditions and target products.
