Phenoxy-(Chloro) _n -Boron Subnaphthalocyanines: Alloyed Mixture, Electron-Accepting Functionality, and Enhanced Solubility for Bulk Heterojunction Organic Photovoltaics.

ABSTRACT: The first set of phenoxy BsubNc compounds, PhO-Cl _n BsubNc and F₅-Cl _n BsubNc, was synthesized through an axial displacement reaction of Cl-Cl _n BsubNc with phenol and pentafluorophenol (respectively). Like their precursor, the products were found to be an alloyed mixture of phenoxylated Cl _n BsubNcs with random positioning in the solid state yet consistent frequency of bay position chlorination. The average bay position chlorine occupancy was determined to be 0.99 through single crystal diffraction of PhO-Cl _n BsubNc. Although the phenoxylation of Cl-Cl _n BsubNc did not influence the chromophore photophysical properties, the electrochemical behavior was found to be more s
