Modified boron subphthalocyanines with stable electrochemistry and tuneable bandgaps†
Abstract
The synthesis of boron subphthalocyanines (BsubPc) from modified phthalonitriles is reported. The BsubPcs have intense red-shifted absorption compared to normal BsubPcs and readily tuneable optoelectronic properties including enhanced electrochemical stability and the presence of up to two reversible electrochemical reductions.
