A series of pyrazine-based linear and angular shaped push-pull chromophores were synthesized by Sonogashira reaction and were further investigated by X-ray analysis. The photophysical properties were comprehensively studied both experimentally and through quantum chemical methods. The drastic influence of the electron-donor and acceptor on the absorption and emission spectra of the linear and angular scaffolds was established. Quantum chemical computations provided a reliable theoretical rationalization of the observed spectral features. These results suggest that extending the conjugation of a pyrazine acceptor in a linear direction can dramatically improve the intramolecular charge transfer interactions.
