Spectroscopic and Biological Properties of the 3-Imino-1,8-naphthalimide Derivatives as Fluorophores for Cellular Imaging.

ABSTRACT: This paper presents the photophysical and biological properties of eight 3-imino-1,8-naphthalimides. The optical properties of the compounds were investigated in the solvents that differed in their polarity (dichloromethane, acetonitrile, and methanol), including three methods of sample preparation using different pre-dissolving solvents such as dimethyl sulfoxide or chloroform. In the course of the research, it was found that there are strong interactions between the tested compounds and DMSO, which was visible as a change in the maximum emission band (λ_em) of the neat 3-imino-1,8-naphthalimides (λ_em = 470-480 nm) and between the compounds and DMSO (λ_em = 504-514 nm). The shift of the emission maximum that was associated with the presence of a small amount
