their associated photophysical behavior. In CH2Cl2, independent of the applied concentration in the range 10−6–10−3 M, all PtII complexes exhibit bright phosphorescence centered at around 520 nm, which is characteristic for monomeric PtII complexes. In stark contrast, the single‐crystal X‐ray structure determination of [Pt(C4pz)2] (1) shows the formation of a dimeric aggregate with a notable Pt⋅⋅⋅Pt contact

of bis-(boron difluoride) complexes 1a–c derivedfrom substituted tetraketonates 2a–c are reported, and their mesomorphic and optical properties have been investigated. Two single crystals of mesogenic ligand 2a (n = 6) and nonmesogenic diboron complex 1a (n = 14) were obtained, and their single crystal and molecular structures were resolved. Results show that all 2a ligands (n = 6, 8, 10, 12, 14) formed
