Biarylvinylcontaining

Biarylvinylcontaining refers to organic molecules that possess both a biaryl moiety and a vinyl group within their structure. The biaryl unit consists of two aryl rings connected by a single bond, leading to a system with restricted rotation around the inter-ring bond. This restricted rotation can give rise to atropisomerism, where different spatial arrangements of the aryl rings are stable and can be isolated. The vinyl group is a two-carbon unsaturated hydrocarbon unit, characterized by a carbon-carbon double bond.

The combination of these two functional groups in biarylvinylcontaining compounds can lead to interesting photophysical and electronic properties. The extended pi-conjugation across the biaryl system and the vinyl group can influence their light absorption and emission characteristics, making them potential candidates for applications in organic electronics, such as organic light-emitting diodes (OLEDs) or organic photovoltaics (OPVs). The specific arrangement and substituents on the aryl rings of the biaryl portion, as well as the positioning of the vinyl group, can be systematically varied to tune these properties. Synthesis of biarylvinylcontaining molecules often involves cross-coupling reactions, such as Suzuki or Heck couplings, to construct the biaryl framework and introduce the vinyl functionality. These compounds are of interest in materials science and medicinal chemistry due to their unique structural features and potential for diverse applications.
