Comparison Study of the Site-Effect on Regioisomeric Pyridyl–Pyrene Conjugates: Synthesis, Structures, and Photophysical Properties

To investigate the “site effect” of pyridyl substituents on a pyrene core, four regioisomeric monopyridyl-pyrene (1–4) and five regioisomeric dipyridyl-pyrene (5–9) conjugates were synthesized and ...
