Carboranes with an icosahedral cluster structure have unique structural features that can induce charge localization in between the carbon and the boron atoms. Depending on the carbon positions, such charge localization is much differentiated. While m- and p-carboranes induce less charge separation, o-carborane exerts the most charge separation in its cluster bonding. In particular, charge localization at the carbon-carbon bond in o-carborane plays a pivotal role in bringing up new types of photochemical processes when photo-functional groups are incorporated into the cage carbon atoms. Fundamental aspects of carborane based photochemistry as well as its applicability for photonic materials will be discussed.
