Environment??Sensitive Fluorophores with Benzothiadiazole and Benzoselenadiazole Structures as Candidate Components of a Fluorescent Polymeric Thermometer
Abstract An environment-sensitive fluorophore can change its maximum emission wavelength (λ em), fluorescence quantum yield (Φ f), and fluorescence lifetime in response to the surrounding environment. We have developed two new intramolecular charge-transfer- type environment-sensitive fluorophores, DBThD-IA and DBSeD-IA, in which the oxygen atom of a well-established 2, 1, 3-benzoxadiazole environment-sensitive fluorophore, ...
