Basic Information
Product Name: Fluorene
Chemical Formula: C13H10
CAS Number: 86-73-7
Appearance: Colorless flaky crystals in pure form; may exhibit slight fluorescence when exposed to air for long periods (due to photooxidation).
Solubility:Poorly soluble in water (<0.1 g/100 mL, 25°C); highly soluble in organic solvents such as diethyl ether, benzene, carbon disulfide, and hot ethanol.
Melting point: 116°C;
Boiling point: 295°C (at atmospheric pressure), capable of sublimation at high temperatures.
Density (20°C): 1.203 g/cm³;
Fluorescent Property: Emits blue fluorescence under UV light, serving as a key component in early fluorescent materials.
Applications
Polymer Materials
Polyfluorene (PF) and Derivatives:
Key conjugated polymers used in organic light-emitting diodes (OLEDs), polymer solar cells (PSCs), and field-effect transistors (FETs).
Example: 9,9-dioctylpolyfluorene is a core component of green-light-emitting materials in OLEDs.
Synthetic Resins: Incorporating fluorene structures into epoxy resins or polycarbonates enhances thermal stability and optical transparency (e.g., photoresists, optical lenses).
Pharmaceuticals and Pesticides
Pharmaceutical Intermediates: Used in synthesizing anticonvulsants and sedatives (e.g., benflumetol, an antimalarial drug);
Insecticides: Certain fluorene derivatives exhibit insect antifeedant activity.
Dyes and Fluorescent Materials
Fluorenone-based dyes (e.g., fluorescein) for textile printing, dyeing, and leather coloring;
Fluorene derivatives as fluorescent probes for bioimaging or environmental detection (e.g., heavy metal ion recognition).
Other Applications
Perfume Fixatives: Fluorene derivatives in the fragrance industry to prolong aroma persistence;
Lubricant Additives: Improve high-temperature stability of lubricants;
Analytical Reagents: Used for ozone concentration determination (based on fluorene oxidation).
Safety and Protection
Hazards
Health Risks:
Inhalation/ingestion: Irritates the respiratory and digestive tracts; long-term exposure may damage the liver and kidneys (LD50 (rat, oral) ≈3000 mg/kg, low toxicity);
Skin contact: May cause mild irritation or allergic reactions.
Environmental Risks:
Poorly biodegradable, potentially harmful to aquatic life through long-term accumulation (LC50 (fish) >10 mg/L, moderate toxicity);
Listed as a priority-controlled pollutant in some countries.
Safety Measures
Wear dust masks, protective gloves, and goggles during operation;
Store in a cool, dry place, away from oxidizers, strong acids, and food;
Extinguish fires with CO2, dry powder, or foam extinguishers; avoid water jets.
