This study reports the facile syntheses of tetra‐boron difluoride (tetra‐BF2) complexes, flag‐
hinge‐like molecules that exhibit intense green‐to‐orange luminescence in solution and …

5586 J. Am. Chem. Soc. 1988, 110, 5586-5588 were occasionally formed. 10 Stelzer
reported the low yield preparation of (fPr2PCH2CH2CH2)((Pr) PCH2P (iPr)-(CH2CH2CH2P …

Furfuryl alcohol can be transformed in a simple way into the long‐awaited sulfur analog of
porphyrin, the tetrathiaporphyrin dication 1, isolated as the perchlorate. The key to the …

Porphycene photosensitizers bearing two or four methoxyethyl side chains were
synthesized in nine steps from commercially available starting materials. Ether cleavage led …

Going around in circles: The copper (I)‐mediated annulation of a doubly 1, 3‐butadiyne‐
bridged carbazole dimer with amines or Na 2 S provides isophlorins containing carbazole or …

Organic field‐effect transistors incorporating planar π‐conjugated metal‐free macrocycles
and their metal derivatives are fabricated by vacuum deposition. The crystal structures of [H2 …

Porphycenes are electronic isomers of porphyrins which, when neutral, display no
appreciable photosensitizing action towards Gram-negative bacteria. The covalent binding …

Abstract Porphyrin (P), porphycene (Pc), corrphycene (Cn), and hemiporphycene (Hpc)
represent a series of well defined “4‐N in” constitutional porphyrin isomers. These isomers …

The first facile syntheses of free‐base di‐and tetrabenzoporphycenes and their metal
complexes are reported, based on retro‐Diels–Alder reactions of the corresponding bicyclo …
