The present invention relates to a family of compounds derived from 5-bromo-7-azaindole to which alkyl chains have been incorporated in one of the nitrogens to make them soluble in organic solvents as well as the incorporation in the position 5 of 4-(diphenylamino)phenylboronic acid derivatives. These structural modifications increase the emission of the derivative in a solid state. The incorporation of aldehyde and cyanoacetic acid derivatives in position 3 facilitates the attachment thereof in different systems. Given this characteristic, they may be applicable in the development of solid-state luminescent materials used in applications of detection, biomedical applications, solid-state illumination, as well as optoelectronic devices.
