摘要：

A chemical strategy to efficiently perform the dimerization of alpha-fused boron-dipyrromethene (BODIPY) is reported. The straightforward synthesis of one of these dimers is described and its properties have been investigated through UV/Vis spectroscopy, cyclic voltammetry, differential scanning calorimetry, and charge-carrier mobility measurements by using organic field-effect transistors and space-charge-limited current diodes. The results allow a chemical strategy to decrease the tendency of alpha-fused BODIPY to crystallize, to increase its light-harvesting properties, and to promote isotropic charge carriers transport. Moreover, the disclosed approach is also a way to maintain the deep LUMO level of alpha-fused BODIPY; thus making this class of materials highly desirable for optoelectronic applications.
