Triazole refers to a heterocyclic compound with the molecular formula C2H3N3, which has a five-membered ring consisting of two carbon atoms and three nitrogen atoms. Neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease already affect many people around the world, and these numbers are increasing rapidly. Treatment for these disorders is often aimed at relieving symptoms and has no cure. Research on new molecules is underway, and heterocyclic compounds have important pharmacological implications. Triazoles and tetrazoles are emerging as new molecules in this field.
Fluorene is a polycyclic aromatic hydrocarbon insoluble in water and soluble in many organic solvents. Fluorenes are one of the most important fluorescent molecules with applications in polymers, electronic devices, sensors, and photochromic materials.
