Web24 Dec 2016 · No, the biphenyl above is not chiral. 2,2′,6,6′-tetrasubstituted biphenyls are nonplanar at room temperature in order to avoid steric clashes between the substituents. This can in general give rise to chirality depending on the substituents, such as in this example. However, this chirality is only true under certain conditions, namely: Web11 Mar 2024 · Biphenyl was chosen as a potentially mesogenic fragment due to the following circumstances. Biphenyl-based low-molecular compounds do not exhibit LC properties [ 2 ]. At the same time, polymer compounds (polyesters) with biphenyl as a mesogen form stable LC phases in a wide temperature range [ 3, 4 ].
