Many of a macromolecule's fundamental characteristics are determined by that molecule's degree of polymerization, but the molecule's physical structure also makes a significant contribution to its macroscopic properties. The terms configuration and...

In chemistry, conformational isomerism is a form of stereoisomerism involving the phenomenon of molecules with the same structural formula existing as different conformational isomers or conformers due to atoms rotating about a bond. There are three...

ABSTRACT The association of protein subunits to form N-mers (N ≥ 3) does not follow the dependence on the law of mass action predicted by the classical thermodynamic description used for the equilibrium of association of small molecules. For those anomalous cases, a...

Symposium-in-Print Photoisomerization of Stilbene Dendrimers: The Need for a Volume-conserving Isomerization Mechanism# ABSTRACT Highly branched stilbene dendrimers were synthesized and their photochemical behavior was studied. Even the stilbene dendrimer with molecular weight over 6500 underwent transcis isomerization in the excited singlet...
