Phthalocyanine nanobars obtained by using alkyloxy substitution effects

The organization of phthalocyanines (Pcs) into controlled structures is essential for their applications in electrical and optical molecular devices. Controlled self-assembly of Pcs from continuous films (CuPcOC8) to nanobars (CuPcOC4) are demonstrated by modulation of alkyloxy substitutions. Such studies could provide possible venues for achieving controllable molecular assembling structures.
