Abstract
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.

A compound having the formula:
- wherein
- X is selected from the group consisting of O and S;
- R1 and R2 are independently selected from the group consisting of hydrogen, C1-C6 alkyl, hydroxy C1-C6 alkyl, and phenyl;
- and
- R3 and R4 come together to form one of a benzo ring, a heteroaryl ring, and a substituted heteroaryl ring, wherein the heteroaryl substituents are one or more of amino, C1-C6 alkyl, and amino C1-C6 alkyl.
