2,7-Dibromo-9,9-diet - Introduction
2,7-dibromo-9, 9-diethylfluorene (abbreviated as DBDT) is an organic compound with the chemical formula C18H22Br2.
Nature:
-Appearance: DBDT is a pale yellow to yellow crystalline solid.
-Melting point: About 70-74 degrees Celsius.
-Solubility: DBDT is almost insoluble in water, but can be dissolved in organic solvents, such as ethanol and ether.
-Stability: DBDT is relatively stable at room temperature.
Use:
-As an intermediate in Organic Synthesis: DBDT can be used to synthesize a series of organic compounds, such as coordination compounds, fluorescent dyes, conductive polymers, etc.
-Used in organic electronic devices: DBDT can be used as a material for organic electronic devices such as organic light-emitting diodes (OLEDs) and solar cells.
Method:
The preparation method of DBDT is usually realized by chemical synthesis, and the specific preparation steps include the following processes:
-The first step is to obtain 2,7-dibromo-9, 9-diethylfluorene precursor: react ethyl lithium and fluorene to obtain ethyl fluorene, and then react in the presence of bromine to obtain 2,7-bis-bromofluorene.
-The second step is to obtain 2,7-dibromo-9, 9-diethylfluorene: 2,7-dibromofluorene is reacted with less reactive bromoethane to generate 2,7-dibromo-9, 9-diethylfluorene.
Safety Information:
- DBDT has no obvious toxicity to human body under general conditions. However, appropriate laboratory practices and personal protective measures should be taken, such as wearing gloves, goggles and protective equipment for laboratory outings.
- DBDT should be kept away from fire and oxidizing agents, and avoid contact with strong oxidizing agents and strong acids.
-Please store the DBDT properly and ensure that the container is well sealed to prevent contact with moisture, so as not to affect its stability and performance.
