FLUORESCENT AROMATIC SENSORS AND THEIR METHODS OF USE

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.

Electrocycloreversion of benzocyclobutenols promoted by photoinduced electron transfer

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.

High Intensity, Argon Ion Laser-Jet Photochemistry

A new technique for the study of high intensity solution photochemistry has been developed.With this laser-jet technique, a high velocity microjet is irradiated with the focussed output of an argon ion laser.Under these extremely high intensity conditions, photochemically generated transient species with suitable absorption properties are excited further and produce relatively large amounts of photoproducts which are not observed under low intensity conditions.The application of this laser-jet technique in the study of the photochemistry of radicals, biradicals, photoenols and the higher excited states of carbonyl and polycyclic aromatic compounds is described.
