An unsymmetrical subphthalocyanine trimer consisting of three different subphthalocyanine units was synthesized. Its optical and physical properties were investigated by UV/Vis, fluorescence spectrometry, cyclic voltammetry and computations. Energy transfer from the non-substituted subphthalocyanine unit to the perfluorinated subphthalocyanine unit via a trifluoroethoxy substituted unit is sugg...

A new class of double-wheel molecules is manipulated on a Au(111) surface by the tip of a scanning tunneling microscope (STM) at low temperature. The double-wheel molecule consists of two subphthalocyanine wheels connected by a central rotation carbon axis. Each of the subphthalocyanine wheels has a nitrogen tag to monitor its intramolecular rolling during an STM manipulation sequence. The posi...

Conventional conjugated systems are characteristic of only either inherent or induced chirality because of synthetic challenge in combination of chiral segment into the main chromophore. In this work, chiral binaphthyl segment is directly fused into the central chromophore of a subphthalocyanine skeleton, resulting in a novel type of chiral subphthalocyanine analogue (R/S)-1 of integrated inher...

The treatment of boron(III) subphthalocyanine chloride with 1,3-bis[3-(diethylamino)phenoxy]propan-2-ol 2 and 2,3-bis[3-(diethylamino)phenoxy]propan-1-ol 4 in toluene gave the corresponding axially substituted boron(III) subphthalocyanine compounds 3 and 5. The novel axially diethylaminophenoxypropanoxy substituted subphthalocyanines were characterized by standard spectroscopy methods. The elec...

The title compound, C(24)BBrF(12)N(6) or Br-F(12)BsubPc (BsubPc is boronsubphtalocyanine), has a bowl-shaped structure with an approximate mol-ecular C(3v) symmetry characteristic of boronsubphthalocyanine compounds. In the crystal, mol-ecules are arranged in one-dimensional columns and the boron-subphthalocyanine units within each column are offset and angled in a bowl-to-ligand packing arrang...

Very efficient stabilization of the photoinduced charge-transfer state was achieved in simple subphthalocyanine-ferrocene dyads, reaching radical pair lifetimes of about 0.2 ms.

A kinetic mixture of self-assembled subphthalocyanine-based capsules was shown to gradually reorganize into its more stable symmetrical components by electrospray mass spectrometry.

Photoredox chemical reactions induced by visible light have undergone a renaissance in recent years. Polypyridyl dyes such as Ir(ppy)3 and Ru(bpy)3 are key catalysts in this event, and blue- or white-light irradiation is required for the chemical transformations. However, it remains a challenge to achieve reactions under the lower energy of red light. We disclose, herein, that trifluoroethoxy-c...

A β,β-sp(3)-hybridized subphthalocyanine analogue, dibenzosubtriazachlorin, was synthesized, and its significantly split Q band absorptions in longer and shorter wavelength regions relative to those of subphthalocyanines were revealed. The effect of benzo-annulation to a subtriazachlorin structure on the position of the split Q bands as well as the electronic structures was also investigated.

The future's wheel: A new class of wheels, based on subphthalocyanine fragments, for future incorporation in functional nanovehicles is reported (see figure). The syntheses of a symmetric wheel, a nitrogen-tagged wheel, and their ethynyl-bridged homodimers are presented. Theoretical calculations and STM imaging demonstrate the advantage of a bowl-shaped structure and the efficiency of the tag f...
