Bis (1 - phenyl - isoquinoline) (Acetylacetonato) iridium (III), that is, bis (1 - phenyl - isoquinoline) (acetylacetonate) iridium (III), this is an organometallic complex, which is widely used in organic Light Emitting Diode (OLED) and other fields. Its physical properties are as follows:
- ** Appearance and morphology **: Usually in a solid state, the specific morphology may be affected by the preparation method and conditions, or it is a crystalline powder, or a bulk crystal, with a clean and glossy appearance.
- ** Melting point **: The melting point is relatively high, usually between 200 ° C and 300 ° C. This higher melting point is due to strong intra-molecular and inter-molecular interactions, such as coordination bonds, van der Waals forces, and π-π stacking, which make the molecules closely aligned and require higher energy to destroy the lattice structure and cause it to melt.
- ** Solubility **: In common organic solvents, such as dichloromethane, chloroform, toluene, etc., it exhibits a certain solubility. This is due to the presence of organic ligands in its molecular structure, which make the molecules hydrophobic and can form moderate interactions with organic solvent molecules, thereby promoting dissolution. However, the solubility in water is very poor, because the overall molecular polarity is relatively small, it is difficult to form effective interactions with water molecules. < Br > - ** Color **: Generally shows a specific color, usually orange-red. This color is derived from the electron transition in the molecule. When light is irradiated, the electrons in the molecule absorb specific energy photons and transition from the ground state to the excited state. The energy difference between different energy levels corresponds to the absorption and emission of specific wavelengths of light in the visible light region, so it appears orange-red.
- ** Luminescence characteristics **: It has excellent luminescence properties and can emit efficient and stable light under electroluminescence or photoluminescence conditions. Its luminescence mechanism is based on the intramolecular charge transfer process. When excited, electrons transfer between the ligand and the central iridium ion, and then return to the ground state and emit photons through radiation transition. The emission spectrum has a relatively narrow half-peak width and high luminescence purity, which makes it possible to achieve high color purity display in OLED display technology.

To prepare bis (1-phenylisoquinoline) (acetylacetone) iridium (III), the first step is to prepare the raw materials, including 1-phenylisoquinoline, acetylacetone and iridium-containing compounds.
Before the reaction, wash and dry the utensils used to prevent impurities from interfering.
Dissolve 1-phenylisoquinoline in an appropriate amount of organic solvent, such as dichloromethane or toluene, to form a uniform solution and place it in the reaction vessel.
Take another iridium-containing compound, such as iridium trichloride, and also dissolve it in an appropriate solvent. Slowly pour it into the solution containing 1-phenylisoquinoline, and stir at the same time to make the two fully mixed.
After that, acetylacetone is added to the above mixture. At this time, the reaction system may change color and other phenomena. Stir continuously to control the reaction temperature, usually heated moderately, such as 60-80 degrees Celsius, to promote the reaction. The reaction time may take several hours to ten hours, depending on the reaction process, which can be monitored by thin layer chromatography (TLC).
After the reaction is completed, cool the reaction liquid, or see the precipitation precipitated, and collect the precipitation by filtration. The obtained crude product is impure and needs to be further purified. The recoverable column chromatography uses silica gel as the stationary phase and a suitable eluent to separate the product from the impurities. Pure bis (1-phenylisoquinoline) (acetylacetone) iridium (III) can be obtained by collecting the eluent containing the target product and evaporating the solvent. It is a metal-organic compound with specific structures and properties, which can be used in organic electroluminescence and other fields.

Bis (1-phenyl-isoquinoline) (Acetylacetonato) iridium (III), a metal-organic compound. Its stability is related to multi-terminal elements.
In terms of chemical structure, the chemical bond between the central iridium (III) ion and the surrounding ligand is stable. The 1-phenyl-isoquinoline ligand is coordinated with the iridium ion by nitrogen and aromatic rings to form a planar structure, which increases the stability of the complex. The acetylacetonate ligand is connected to the iridium ion in the form of didentate, forming a five-membered chelating ring, which also significantly enhances the stability. This chelating effect makes the ligand tightly bound to the central ion and difficult to dissociate.
From the perspective of electronic effects, the electron-giving ability of ligands has a significant impact on stability. Both 1-phenyl-isoquinoline and acetylacetone ligands have electron-giving properties, which can transfer the electron cloud density to the central iridium ion and enhance the interaction between it and the ligand. In this way, the metal-ligand bond energy increases, and the stability of the complex is improved.
Environmental factors should not be underestimated. Under normal temperature and moderate humidity, the compound has good stability. However, if the temperature is too high, the molecular thermal motion may increase, which may increase the vibration amplitude of the metal-ligand bond, weaken the bond energy and reduce the stability. If the humidity is too high, the moisture may interact with the compound, triggering reactions such as hydrolysis, which affects the stability. And the compound has good solubility in organic solvents and can remain stable in suitable solvents. However, some special solvents may chemically react with the compound, reducing the stability.
In summary, the stability of Bis (1-phenyl-isoquinoline) (Acetylacetonato) iridium (III) depends on various factors such as its own chemical structure, electronic effects and external environment. If all factors are suitable, this compound can maintain high stability.

First, the purity of the product has a huge impact on the price. If the purity is extremely high, it can reach the level of scientific research, and can be accurately used for high-end experimental research, the price will be high. On the contrary, if the purity is slightly lower, it is only suitable for general industrial use, and the price will be relatively low.
Furthermore, the market supply and demand conditions also affect the price. If the market demand for the compound is strong and the supply is limited, if the demand for it in a specific industry increases sharply, resulting in a shortage of supply, the price is bound to rise; if the market demand is low and the supply is sufficient, the price will drop.
In addition, the price varies depending on the manufacturer. Well-known large factories, with advanced production technology and strict quality control, have high product quality and high prices; some small factories, although the cost control is good, the product quality stability may be insufficient, and the price may be relatively close to the people.
According to past market conditions and relevant experience, the price may range from tens of yuan to thousands of yuan per gram. This is only a rough estimate. The actual price will fluctuate due to the above factors. When purchasing, you need to consult various suppliers in detail to obtain accurate prices.
