Chemical Reactivity: The hydrogen atoms on the rings are somewhat reactive and can undergo substitution reactions under appropriate conditions, such as electrophilic substitution reactions with halogenated hydrocarbons and acyl halides. They can also serve as ligands to form complexes with metal ions.
Applications: These compounds have promising applications in medicinal chemistry and materials science. In medicinal chemistry, their derivatives may possess antibacterial and antitumor activities. In materials science, they can be used to construct functional materials with unique optoelectronic properties.
