Predicting precursor size effects on organic cage formation with molecular dynamics
The recently developed porous organic molecular cage is a promising class of porous materials, which has already opened new ways for specific reaction environment development, molecular separation and storage, and catalysis. Creation of these small porous cage molecules is challenging because there …
