Abstract: The present invention relates to functionalizing a surface of an organic material. For example, surfaces of materials having C—H bonds, such as polymers having C—H bonds, can be functionalized. In certain embodiments, a heterobifunctional molecule having a photoactive anchor, a spacer, and a terminal functional group is applied to the surface of an organic material that contains one or more C—H bonds. The heterobifunctional molecule can be bound to any surface having C—H bonds as the photoactive anchor can react with C—H bonds upon irradiation. The terminal functional group has a “click” functionality which can be utilized to functionalize the surface of the organic material with any desired functionalizing moiety having the orthogonal click functionality.
