We are reporting the unexpected reaction between bromo-boron subphthalocyanine (Br-BsubPc) and THF, 1,4-dioxane or γ-butyrolactone that results in the ring opening of the solvent and its addition into the BsubPc moiety. Under heating, the endocyclic C-O bond of the solvent is cleaved and the corresponding bromoalkoxy-BsubPc derivative is obtained. These novel alkoxy-BsubPc derivatives have rema...

Novel subphthalocyanine analogues that display strong absorption in the green region have been synthesized by using a boron template cyclotrimerization of maleonitrile derivatives. The spectroscopic properties of these macrocycles indicate that, like subphthalocyanines, they have 14 pi electrons and are aromatic compounds with a conical shape. The removal of the three fused benzene rings from t...

Abstract A boron subphthalocyanine molecule has been employed as a novel electron donor in organic solar cells (OPVs), and optimized terms of composition device structure small cells. It is demonstrated that the power conversion efficiency (PCE) devices obtained by solution-processing bulk heterojunction could be improved one order magnitude changing fabrication method to vacuum deposition, whi...

The great potential of subphthalocyanines (SubPcs) to stabilize boron peroxides has been demonstrated. In particular, a subphthalocyanato (III) peroxide prepared in good yield via triflate. This derivative is remarkably stable under ambient conditions and can be fully characterized. impact the group on structural optoelectronic properties SubPc was examined by NMR UV/Vis spectroscopies, as well...
