The present invention describes tripodal catechol derivatives with a flexible basic framework for the functionalisation of surfaces, and methods for their production and use. The central atom of the flexible framework is hereby a tertiary aliphatic carbon atom. The remaining fourth bridgehead position is easily suitable to be further functionalised via so-called click reactions, e.g. with biomolecules, dyes, radiomarkers, polyethylene glycol or active agents. 2.
