Morteza Torabi was born in 1995 in Hamedan, Iran. He received his B.Sc. in Applied Chemistry (2017) and M.Sc. in Organic Chemistry (2019) from Bu-Ali Sina University under the supervision of Professor Mohammad Ali Zolfigol. He is currently working towards his Ph.D. under the supervision of Professor Mohammad Ali Zolfigol at Bu-Ali Sina University. His research interest is the design, synthesis ...
In the title inclusion compound, C(26)H(26)N(4)O(6)·C(2)H(4)Cl(2), the solvent mol-ecule occupies a cavity inside the clip-type mol-ecule which is based on the glycoluril skeleton with two ethyl acetate substituents on the convex face of the glycoluril system. The dihedral angle between the aromatic rings of the host is 43.59 (4)° and the centroid-centroid distance is 6.741 (5) Å. The 1,2-dichl...
The synthesis and aggregation behavior of a new class of rigid metallohosts is described. The molecules consist of a ruthenium-bipyridine complex functionalized with a glycoluril-based receptor cavity. By specific molecular recognition processes in water, the metallohosts self-assemble to form large arrays of molecules. Depending on the size of the cavity side walls of the host, these arrays ca...
Ditopic binding of various dinitrogen compounds to three bisporphyrin molecular tweezers with spacers of varying conformational rigidity, incorporating the planar enediyne (1), the helical stiff stilbene (2), or the semi-rigid glycoluril motif fused to the porphyrins (3), are compared. Binding constants Ka = 10⁴-10⁶ M(-1) reveal subtle differences between these tweezers, that are discussed in t...
The title compound, C(36)H(34)N(4)O(4)S(2), is a thio-glycoluril derivative, which bears two phenyl substituents on its convex face and two meth-oxy substituted o-xylylenes as sidewalls of the molecular clip. There is one half-mol-ecule in the asymmetric unit: a crystallographic twofold axis generates the complete molecule. The non-planar seven-membered rings adopt chair conformations, while th...
