Organic semiconductors have been extensively used in
–molecule interactions [1][2][3][4]. Nonplanar MPcs, such as leadphthalocyanine (PbPc), are particularly interesting in the field of photovoltaics due to their extraordinary near-infrared (NIR) absorption. The chemical structure of a PbPc molecule is given in Figure 1. The well-known polymorphs of
