Giant extended π-conjugated dendrimers containing the 10,15-dihydro-5H-diindeno[1,2-a;1′,2′-c]fluorene chromophore: Synthesis, NMR behaviors, optical properties, and electroluminescence

This paper reports the facile synthetic strategy of a series of novel π-conjugated dendrimers (G0 and G1) based on 10,15-dihydro-5H-diindeno [1,2-a;1′,2′-c]fluorene (truxene) in which the benzene cores are generated "in-situ" from acetyl aromatics by the

A palladium(II)-clipped aromatic sandwich

A filling that makes the sandwich: Large aromatic molecules are sandwiched by two π-conjugated ligands (L) that are joined together by six {(en)Pd} 2+ units (M; en = 1,2-ethanediamine; see picture; guest red, {(en)Pd}2+ yellow, ligand blue). This host has an M6L 2 composition and is distorted by the concave shape of the ligand. Without a guest, it releases the distortion by forming the dimeric M 12L4 in a reversible fashion.

High-spin polyphenoxyls attached to star-shaped poly(phenylenevinylene)s

Star-shaped poly(1,2-phenylenevinylene)s 4-substituted with multiple pendant phenoxyls (2 and 3) were synthesized by polymerizing 2-bromo-4-(acetoxyphenyl)styrene in the presence of 1,3,5-triiodobenzene or 1,3,5-tris(3′,5′-diiodophenyl)benzene as the core via a simple one-pot Heck reaction and subsequent hydrolysis, phenolate formation, and heterogeneous oxidation. ESR spectra indicated a delocalized spin distribution into the core parts of the star-shaped molecules. The polyradicals, 2 and 3, were in a high-spin state at low temperature, and the ferromagnetic behavior was enhanced for the polyradical with a higher molecular weight. Although an average S of 3 remained at 3/2 to 4/2, the polyradical 2 even with a spin concentration of 0.8 spin/unit revealed an average S of 7/2 to 8/2. The 1,3,5-benzene core acted as an effective magnetic coupler to align the spins of the pendant phenoxyls through the star-shaped π-conjugated backbone.

Synthesis and characterization of a series of monodisperse, 1,3,5-phenylene-based hydrocarbon dendrimers including C276H186 and their fluorinated analogues

The convergent synthesis of a series of monodisperse aromatic dendrimers having molecular diameters of 15-31 ? is described. These materials consist of 4, 10, 22, or 46 benzene rings linked symmetrically by σ-bonds. Increasingly large dendrimer arms are p
