Pyrazolo[1,5-a]pyrimidines-based fluorophores: a comprehensive theoretical-experimental study.

ABSTRACT: Fluorescent molecules are crucial tools for studying the dynamics of intracellular processes, chemosensors, and the progress of organic materials. In this study, a family of pyrazolo[1,5-a]pyrimidines (PPs) 4a-g has been identified as strategic compounds for optical applications due to several key characteristics such as their simpler and greener synthetic methodology (RME: 40-53%) as compared to those of BODIPYS (RME: 1.31-17.9%), and their tunable photophysical properties (going from ε = 3320 M^-1 cm^-1 and ϕ _F = 0.01 to ε = 20 593 M^-1 cm^-1 and ϕ _F = 0.97), in which electron-donating groups (EDGs) at position 7 on the fused ring improve both the absorption and emission behaviors. The PPs be
