Functionalization of [C60]-Fullerene: A Recent Update

Functionalization of fullerene has garnered great attention owing to its unique structural, electronic, and photophysical properties. The distinctive properties of fullerene derivatives make them a multifaceted candidate for application in photochemical, biological, nanomaterial, and photophysical studies. The radical scavenging properties of fullerene owe them an important role in reactive oxygen species (ROS) capturing applications. The organic photovoltaic cells are fabricated utilizing functionalized fullerenes due to its electron-accepting properties. The increased prominence of functionalization led to different innovative methodologies to bloom. The present review focuses on various synthetic strategies were adopted for [C-60]-annulation reactions to accomplish carbo- and heterocycles fused fullerenes from early 2014 to till date.
