Nanographenes: The successful synthesis of a dendritic nanographene is reported. [19]Dendriphene, which is the largest unsubstituted cata‐condensed nanographene obtained by solution chemistry, was characterized on‐surface by scanning probe microscopy.

Abstract

The synthesis of a threefold symmetric nanographene with 19 cata‐fused benzene rings distributed within six branches is reported. This flat dendritic starphene, which is the largest unsubstituted cata‐condensed PAH that has been obtained to date, was prepared in solution by means of a palladium‐catalyzed aryne cyclotrimerization reaction and it was characterized on surface by scanning probe microscopy with atomic resolution.

A large‐scale selective synthesis of a C _2v‐symmetric hexaphenylbenzene (HPB) derivative with three kinds of substituents on the periphery of HPB was realized using inexpensive reagents.

Abstract

A large‐scale selective synthesis of a C _2v‐symmetric hexaphenylbenzene (HPB) derivative with three different kinds of substituents on the periphery of HPB was realized using inexpensive reagents. All the reactions were carried out at room temperature or by heating and most materials along the synthetic route could be isolated without chromatographic purification.

The best things come in threes: Triply linked porphyrin arrays, so called porphyrin tapes, are intriguing molecules in terms of their stability, far red‐shifted absorption band, multi‐charge storage ability, and conductivity. Recent advances in the chemistry of porphyrin tape are summarized in this Minireview, in particular, the development of porphyrin tape variants such as expanded porphyrin hybrid tape, porphyrin arch‐tape, corrole tape, and subporphyrin tape.

Abstract

Triply linked porphyrin arrays, so called porphyrin tapes, are intriguing molecules in terms of their planar structures, far red‐shifted absorption bands, multi‐charge storage abilities, and high conductivities. Recently, porphyrin tape variants such as porphyrin‐expanded porphyrin hybrid tapes, porphyrin arch‐tapes, corrole tapes, and a subporphyrin tape have been explored as novel π‐conjugated materials. These new molecules exhibit electronic and structural characteristics owing to direct triple linkages. This Minireview first discusses the fundamental properties of the parent porphyrin tapes and the peripherally functionalized porphyrin tapes. Then, a focus has been placed on the syntheses, structures, and unique properties of the recently explored porphyrin tape variants.
