Subphthalocyanine capsules: molecular reactors for photoredox transformations of fullerenes

Abstract

The internal cavity formed by a dimeric subphthalocyanine (SubPc) capsule (SubPc2Pd3, 2), ensembled by coordination of pyridyl substituents in the monomeric SubPc 1 to Pd centers, has proved an optimal...

Synthesis, Optical Properties, and Fluorescence Cell Imaging of Novel Mixed Fluorinated Subphthalocyanines

“…A crystal of 6 was obtained by slow vapor diffusion ( n -hexane into CH 2 Cl 2 ), and its structure was determined by X-ray diffraction analysis. It showed an essentially bowl-shaped structure similar to that of the general SubPcs (0.56–0.66 Å) [ 34 ], with a deviation of a boron atom by 0.601 Å from the mean plane defined by three boron-coordinating nitrogen atoms ( Figure 2 ). The bowl depth from the boron atom to the second plane defined by peripheral halogen atoms was 2.310 Å, similar to that for the reported SubPcs (2.45–2.75 Å) [ 35 , 36 ].…”

Modular synthesis, host–guest complexation and solvation-controlled relaxation of nanohoops with donor–acceptor structures

“…Recently, several C 60 hosts have been prepared to realize different functions. 32 As a well-studied C 60 host, [10]CPP possessed ideal size complementarity for encapsulating C 60 with noncovalent van der Waals (vdW) interaction. 33 Considering that C 60 is a well-known acceptor itself, it is interesting how nanohoop hosts with D–A features could influence the complexation.…”

Controlling the reactivity of phthalonitriles for the efficient synthesis of chiral phthalocyanines with self-assembly abilities

“…Phthalocyanines 1,2 are fascinating organic compounds with high thermal and optical stability, strong absorption in the visible region, remarkable photophysical properties, semiconducting behaviour and organization abilities, which enable them to be used as targets of choice for a variety of biomedical applications, 3 as photocatalysts, 4 or as active molecules for a variety of optoelectronic devices. 5…”

“…Phthalocyanines 1,2 are fascinating organic compounds with high thermal and optical stability, strong absorption in the visible region, remarkable photophysical properties, semiconducting behaviour and organization abilities, which enable them to be used as targets of choice for a variety of biomedical applications, 3 as photocatalysts, 4 or as active molecules for a variety of optoelectronic devices. 5 Self-condensation of phthalonitriles is by far the most widely used method for the synthesis of Pcs, [6][7][8][9][10] which in many cases is initiated by a nucleophilic attack of a lithium alkoxide (or another strong nucleophile) on the electrophilic carbon of the nitrile, which generates nucleophilic nitrogen that proceeds with the self-condensation process.…”
