Journal ArticleDOI
Self-assembling bisurea macrocycles used as an organic zeolite for a highly stereoselective photodimerization of 2-cyclohexenone.
TL;DR: A highly selective 2 + 2 cycloaddition of 2-cyclohexenone in the presence of self-assembled bisurea macrocycles that yields the head-to-tail photodimer with high conversion and with decreased incidence of secondary photorearrangement is reported.
Journal ArticleDOI
Self-assembled phenylethynylene bis-urea macrocycles facilitate the selective photodimerization of coumarin.
Sandipan Dawn,Mahender B. Dewal,David Sobransingh,Monissa C. Paderes,Arief Wibowo,Mark D. Smith,Jeanette A. Krause,Perry J. Pellechia,Linda S. Shimizu +8 more
TL;DR: The synthesis and self-assembly of an expanded bis-urea macrocycle to give crystals with columnar channels that facilitate the conversion of coumarin to its anti-head-to-head (HH) photodimer with high selectivity is reported here.
Journal ArticleDOI
Absorption properties of a porous organic crystalline apohost formed by a self-assembled bis-urea macrocycle
Mahender B. Dewal,Michael W. Lufaso,Andrew D. Hughes,Stevan A Samuel,Perry J. Pellechia,Linda S. Shimizu +5 more
TL;DR: In this article, the characterization and binding properties of a microporous crystalline host formed by the self assembly of a bis-urea macrocycle 1 have been reported, and the structure of apohost 1 and its inclusion complexes were investigated by powder X-ray diffraction.
Journal ArticleDOI
Origins of Selectivity for the [2+2] Cycloaddition of α,β-unsaturated Ketones within a Porous Self-assembled Organic Framework
TL;DR: In this paper, the origins of selectivity for α,β-unsaturated ketones within a porous crystalline host were investigated. But the authors focused on the 3-methyl-2-cyclopentenone and 2-cyclohexenone.
Journal ArticleDOI
Examination of the structural features that favor the columnar self-assembly of bis-urea macrocycles.
TL;DR: The results suggest that the stacking of the arene units in the rigid first-generation systems was an important factor in guiding the formation of the columnar stacks.
