Organic-based photovoltaics are of great interest due to the ability to solution process the materials and fabricate the devices on flexible substrates. Organic dyes, such as phthalocyanines (Pcs), have been successfully incorporated into vapor deposited photovoltaic devices; however, devices prepared from soluble Pc have exhibited low efficiencies. In an effort to investigate the use of liquid crystalline Pcs for solution processable devices several alkyl substituted Pcs were synthesized. A one pot synthesis has been utilized to prepare a variety of tetra-substituted Pcs. The bulk-heterojunction device properties were investigated an attempts have been made to optimize the device performance.
