1,1'-[(1E,11E)-5,8-Dioxa-2,11-diazo-nia-dodeca-1,11-diene-1,12-di-yl]dinaph-thal-en-2-olate.

ABSTRACT: The title compound, C(28)H(28)N(2)O(4), crystallizes in a zwitterionic form with deprotonated naphthol hy-droxy groups and protonated imine N atoms. The asymmetric unit contains one half-mol-ecule located on a twofold rotation axis. Intra-molecular N-H?O hydrogen bonds occur and the two bicyclic ring systems form a dihedral angle of 64.2?(1)°. In the crystal, weak inter-molecular C-H?O hydrogen bonds link the mol-ecules into layers parallel to the bc plane.

Project description:In the title salt hydrate, C(22)H(30)N(2)O(6) (2+)·2Cl(-)·CH(4)O, the dication adopts a U-shaped conformation whereby the benzene rings are splayed out from the chain linking them. All components of the asymmetric unit are linked into a cohesive entity by a combination of O-H?Cl(-), N(+)-H?Cl(-) and N(+)-H?O charge-assisted hydrogen-bonding inter-actions. The assemblies thus formed are linked into supra-molecular helical chains along [010] via C-H?O contacts. The resulting chains are, in turn, consolidated into the three-dimensional crystal structure by C-H?? contacts.

2,11-Dibromo-5,8-dibut-yl[4]helicene.

Project description:A racemic mixture of the title compound, C(26)H(26)Br(2), a brominated [4]helicene, crystallizes, forming columns of stacked mol-ecules. There are two crystallographically unique mol-ecules in the asymmetric unit, both with the same helical handedness. As is typical with helicene congeners, the unique mol-ecules show short inter-atomic contacts between H atoms at the fjord region, with H?H distances of 1.87 and 1.94?Å. Mol-ecules with the same helical handedness segregate in the crystal packing, forming homochiral columns. The stacked mol-ecules are piled in a column with alternate orientations. The shortest C?C distance in the stacked mol-ecules is 3.306?(4)?Å.

Synthesis, optical properties and crystal structure of (E,E)-1,3-(3,4:9,10-dibenzododeca-1,11-diene-5,7-diyne-1,12-diyl)benzene

Project description:A dehydrobenzannulene, (E,E)-1,3-(3,4:9,10-dibenzododeca-1,11-diene-5,7-diyne-1,12-diyl)benzene, was stereoselectively synthesized, and its crystal structure and UV-Vis absorption and photoluminescence optical properties were determined. The dehydrobenzannulene (E,E)-1,3-(3,4:9,10-dibenzododeca-1,11-diene-5,7-diyne-1,12-diyl)benzene, C26H16, was successfully synthesized via photocatalyst-assisted stereoselective reductive desulfonylation of 1,3-bis{1-phenylsulfonyl-2-[2-(trimethylsilylethynyl)phenyl]ethenyl}benzene, C44H42O4S2Si2, and subsequent desilylative cyclization of the resulting (E,E)-bis-silyl-protected dienyne, C32H34Si2. The structure of the dehydrobenzannulene thus obtained was confirmed by single-crystal X-ray analysis; three benzene rings are connected to one another by a 1,3-butadiynylene and a pair of ethenylene arrays. Although the π-system expanded efficiently in the dehydrobenzannulene, it was observed that the butadiynylene and ethenylene arrays were strained, showing smaller [171.3 (2)–172.6 (2) °] and larger bond angles [122.5 (2)–131.9 (2)°] than the conventional bond angles, respectively. In CHCl3, the dehydrobenzannulene showed the longest absorption band at 377 nm. When irradiated by UV light, it emitted fluorescence at 468 nm (ΦF = 0.26) and 504 nm (ΦF = 0.24) in CHCl3 and in the powdered state, respectively.
