Isomers are compounds with the same molecular formulae but different structural formulae. They have the same number of each type of atom. They can be part of the same or different homologous ...

Electromerism is an unfamiliar concept to many chemists and refers to molecules that are not conventional isomers but instead differ in how the electrons are distributed across their structure.

Sun Qingfu's team from the Fujian Institute of Research on the Structure of Matter ... studied selectively recognized pair of highly similar C 2v-symmetric C 78 isomers, namely C 2v (2)-C 78 ...

However, as the number of isomers increases exponentially in higher fullerenes (C n, n>7), achieving their selective enrichment through molecular recognition remains a challenge. This study ...
