1,4-Di(2-thienyl)-1,3-butadiene - Introduction
Dithienylbutadiene(Dithienylbutadiene) is an organic compound containing thiophene and butadiene groups. It has the following properties:
1. Chemical properties: Dithienylbutadiene is a molecule with a conjugated structure, so it has good photoelectric properties. It can absorb ultraviolet and visible light, and electron transfer and resonance enhancement occur in the excited state.
2. Photoelectric properties: Dithienylbutadiene absorbs in the ultraviolet and visible light regions and produces fluorescence or phosphorescence. Its absorption and emission wavelengths can be controlled by changing its structure and substituents to achieve different colors of light emission.
3. Use: due to the good photoelectric properties of Dithienylbutadiene, it is widely used in organic photoelectric materials, organic light-emitting diodes (OLED), solar cells and sensors and other fields. It can also be used as a fluorescent probe and fluorescent label.
4. Preparation method: the preparation of Dithienylbutadiene can be obtained by the reaction of thiophene and bromobutane, and then the butadiene group can be obtained by elimination reaction. During the preparation process, attention should be paid to the control of ambient temperature and reaction conditions.
5. Safety information: Dithienylbutadiene has low toxicity, but it is still necessary to comply with laboratory safety procedures. Avoid contact with the skin or inhalation of its vapors during handling and storage. When used in the workplace, it is recommended to wear appropriate protective equipment, such as gloves and safety glasses, to avoid accidental exposure.
