Abstract

Phthalocyanines provide an opportunity to directly observe electronic effects in an aromatic system through color changes that are dependent on the nature of peripheral substituents. Simple, reliable syntheses of electron-poor and electron-rich phthalocyanines are reported, along with corresponding UV-visible spectra. This is suitable for a sophomore organic course; both synthetic and physical organic principles may be developed by the instructor.
