Benzocyclobutenols 1 undergo electron-transfer induced electrocycloreversion to generate o-quinodimethane intermediates E-4 and Z-4, which then tautomerize to benzophenones 2. Evidence for the intermediates is provided by the trapping experiments and the laser flash photolysis experiments.
FLUORESCENT AROMATIC SENSORS AND THEIR METHODS OF USE
-
Page/Page column 8, (2008/12/07)
Aromatic molecules that can be used as sensors are described. The aromatic sensors include a polycyclic aromatic hydrocarbon core with a five-membered imide rings fused to the core and at least two pendant aryl groups. The aromatic sensor molecules can detect target analytes or molecular strain as a result of changes in their fluorescence, in many cases with on-off behavior. Aromatic molecules that fluoresce at various frequencies can be prepared by altering the structure of the aromatic core or the substituents attached to it. The aromatic molecules can be used as sensors for various applications such as, for example, the detection of dangerous chemicals, biomedical diagnosis, and the detection of damage or strain in composite materials. Methods of preparing aromatic sensor molecules are also described.
