Building Blocks

Organic building blocks are organic functionalized molecules, the basic components for organic synthesis. They are used for bottom-up modular assembly of molecular architectures such as supra-molecular complexes, metal-organic frameworks, organic molecular constructs and nanoparticles.

Three colorful squares with chemical structures and names on them, placed diagonally from top left to bottom right. The top square is yellow and displays the structure of ‘Furan’ with its five-membered ring including one oxygen atom. The middle square is blue and shows the structure of ‘Thiophene,’ which has a five-membered ring with one sulfur atom. The bottom square is purple and illustrates the structure of ‘Purine,’ a larger, more complex molecule with two rings containing nitrogen atoms.

an illustration of a molecule model with a ring structure against a yellow background. The model consists of gray, green, blue, and red spheres connected by white lines representing chemical bonds. In the center, there is a hexagonal ring formed by six gray spheres, with a green sphere attached to one corner and a blue sphere attached to another. Additionally, a red sphere is connected to one of the gray spheres by two white lines, suggesting a double bond.
Halogenated Building Blocks

Halogenated heterocycles are used in a vast array of synthetic protocols, including lithiation and palladium catalyzed cross-coupling methodologies.
