In this sense, a particularly interesting molecule is the bis(difluoroboron)-1,2-bis-(pyrrol-2-yl)methylene-hydrazine (BOPHY) chromophore (Scheme 1). The BOPHY dye was first discover in 2014 simultaneously by two independent research groups . Since then, its use has exponentially increased in different applications such as sensing , photosensitizer in photodynamic therapy , chemical actinometer , part of up conversion systems , and as the main moiety to prepare conjugated porous polymers CPPs and covalent organic frameworks (COFs) for photocatalysis in solar fuel production or biomedical applications . The BOPHY chromophore consists in four rings, with two pyrrole units at the periphery and two six-membered rings, each incorporating a N2BF2 group in opposite direction (5 and 10 positions). To increase its chemical stability, our target molecule is substituted by four bulky methyl group along its periphery. Additionally, to facilitate the formation of BOPHY-based nanostructures, our precursor monomer has been functionalized with I atoms at the para positions along the molecular longitudinal axis (I-BOPHY-I). In its solid state, the BOPHY chromophore is almost planar attending to x-ray diffraction measurements but some authors suggested that, in solution, the real geometries of S0 and S1 electronic states are highly puckered , making interesting its study at the molecular level on a surface. Interestingly, the I-BOPHY-I molecule is prochiral, exhibiting adsorption-induced chirality when deposited on surfaces. The whole array of such molecular adsorbates is naturally racemic as spontaneous global mirror-symmetry breaking is disfavored .
