Abstract:
A new series of porphyrin(2.1.2.1) arches have been successfully synthesized by using porphyrin(2.1.2.1) as natural "arch limbs" for the construction of the arches. X-ray single-crystal diffraction revealed that the porphyrin(2.1.2.1) derivatives have a beautiful bow-shaped structure. The strong, rigid structure of the porphyrin(2.1.2.1) bow prevents hydrogenation with the Lindlar catalyst. The heterogeneous electrocatalytic HER activity of the porphyrin(2.1.2.1) bow indicated that the "bowstring" butadiyne-bridge reduced the HER capacity.

Globular and Fibrous Proteins
Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...
