Bridging molecules are chemical entities that connect two or more other molecules or parts of a larger molecule. This connection can be temporary or permanent, and the bridging molecule itself can vary greatly in size and chemical composition. In a broader sense, the concept of bridging can be applied in various scientific fields.

In organic chemistry, bridging molecules often refer to atoms or groups of atoms that span across a ring structure, creating a bicyclic system. These bridges can influence the molecule's shape, rigidity, and reactivity. For example, in adamantane, a cage-like hydrocarbon, methylene (-CH2-) groups bridge the six-membered rings. Similarly, in certain polymers, bridging groups can link polymer chains together, creating a cross-linked network.

Beyond organic chemistry, the term can be used analogously. In biochemistry, a bridging protein might connect different cellular components or facilitate the interaction between biomolecules. In materials science, bridging units can be employed to link nanoparticles or other functional units within a composite material. The primary function of a bridging molecule is to establish a spatial or functional link, influencing the overall properties and behavior of the system it is part of. The nature of the bridge, whether it is covalent, ionic, or based on weaker intermolecular forces, dictates the strength and permanence of the connection.
