标 题 :Composition, synthesis, and use of a new class of fluorophores
发明人：BASU PARTHA; SERLI MITASEV BARBARA
权利人:UNIV HOLY GHOST DUQUESNE
摘要:A new class of fluorophores is presented. The fluorophores include a conjugated ring system, such as a dithiolone, a pyran, and a pyrazine containing ring system. The structure is designed with the flexibility to have multiple substitution patterns. The fluorophores may be used in applications including, but not limited to, biomarker applications, pH sensors, metal sensors, and as components for molecular electronics.
