Topology, a well-established concept in mathematics, has nowadays become essential to describe condensed matter. At its core are chiral electron states on the bulk ...
WebThe most common source of chirality in organic compounds is the asymmetric carbon atom. However, it is possible to have molecular chirality without asymmetric carbons. In 1874, Van't Hoff predicted that 1,3-disubstituted allenes (1,2-propadienes) were capable of resolution, i. e., chiral. In 1935, his conjecture was confirmed.

The chiral target displays various solid-state packings from the yellow phase (YP), including crystals, aggregates and gels, to an orange/red phase (OP). The transition from YP to OP can be achieved by applying mechanical stress.

WebIn general, if you have a small molecule with no sp3 centers in the molecule, the molecule is planar. But there are many exceptions. Here are a few common ones: - Water is planar. The oxygen is sp3 but there are only 3 atoms so there's nothing to stick out of the HOH plane. - Allene is not planar.
