An unprecedented cis‐bimetallic complex of dinaphthoporphycene (DNP), namely [Pd2(μ‐DNP)(μ‐OAc)2], is reported. The most striking feature of this complex is that two palladiums coordinate to the macrocycle on the same side and are closely held together (PdPd: 2.67 Å) by two bridging acetate ligands exhibiting significant metal–metal bonding interaction (bond order 0.18 evaluated by NBO analysis). Interestingly, replacing acetate with acetylacetonate (acac) could stabilize an unusual mono‐palladium complex of DNP, where Pd coordinates unsymmetrically to two ring Ns above the macrocyclic plane, as well as coordinating with two Os of the acac ligand. Remarkably, the rigid DNP core displays enhanced complexation induced aromaticity (as per NICS and HOMA analysis), despite undergoing severe core deformation during complexation with metal ion(s) as noticed from their solid‐state structures.

“…Diese Schwingungen werden den Jahn-Te ller-Moden der beiden Jahn-Teller-Isomere zugeordnet.

“…Research in this laboratory has developed the selective auration of carbon skeletons to explore the photophysical consequences of gold attachment. [29][30][31][32][33][34][35] Phosphine-gold(I) fragments are isolobal with a proton. [36] They are soft Lewis acids that activate soft electrophiles, such as p systems.…”

One gold(I)-substituted styrylbenzene, six digold(I) distyrylbenzenes, one tetragold distyrylbenzene, and four digold distyrylnaphthalene complexes were synthesized using base-promoted auration, alkynylation, triazolate formation, and Horner-Wadsworth-Emmons reactions. The gold(I) fragments are either σ-bonded to the aromatic system, or they are attached through an alkynyl or triazolate spacer. Product formation was monitored using (31)P{(1)H} NMR spectroscopy. Systems in which gold(I) binds to the central benzene ring or the terminal phenyl rings were designed. All of these complexes have strong ultraviolet absorptions and emit blue light. The position of the gold(I) attachment influences the luminescence efficiency. Complexes with two gold(I) fragments attached to the ends of the conjugated system have fluorescence quantum yields up to 0.94, when using 7-diethylamino-4-methylcoumarin as the emission standard. Density-functional theory calculations on three high-yielding emitters suggest that luminescence originates from the distyrylbenzene or -naphthalene bridge.
