difluoro-boradiazaindacene fluorophores have been synthesized, and their photophysical and hyperpolarizability properties in various microenvironments were evaluated experimentally and characterized in detail with respect to DFT and TD-DFT using B3LYP/6-31G(d) level of theory. The dyes possess reasonable first order hyperpolarizabilities in solvents of different polarities. The photophysical properties of the di
