Coordinative halogen bonds have recently gained interest for the assembly of supramolecular capsules. Ion
mobility-mass spectrometry and theoretical calculations now reveal the well-defined gas-phase structures
of dimeric and hexameric [N/I
+/N] halogen-bonded capsules with counterions located inside their
cavities as guests. The solution reactivity of the large hexameric capsule shows the intriguing solventdependent
equilibrium between the hexamer and an unprecedented pentameric [N/I
+/N] halogenbonded
capsule, when the solvent is changed from chloroform to dichloromethane. The intrinsic
flexibility of the cavitands enables this novel structure to adopt a pseudo-trigonal bipyramidal geometry
with nine [N/I
+/N] bonds along the edges and two pyridine binding sites uncomplexed.

Design and construction of halogen-bonded capsules and cages
Turunen, Lotta (University of Jyväskylä, 2017)This thesis describes the design, synthesis and characterization of supramolecular halogen-bonded capsules and cages from multivalent ligands. In the first part of the thesis, an overview to halogen bonding is provided. ... -
The “nitrogen effect” : Complexation with macrocycles potentiates fused heterocycles to form halogen bonds in competitive solvents
Twum, Kwaku; Nadimi, Sanaz; Osei, Frank Boateng; Puttreddy, Rakesh; Ojong, Yvonne Bessem; Hayward, John J.; Rissanen, Kari; Trant, John F.; Beyeh, Ngong Kodiah (Wiley-VCH Verlag, 2023)Weak intermolecular forces are typically very difficult to observe in highly competitive polar protic solvents as they are overwhelmed by the quantity of competing solvent. This is even more challenging for three-component ... -
Halogen bonding and host-guest chemistry between N-alkylammonium resorcinarene halides, diiodoperfluorobutane and neutral guests
Pan, Fangfang; Dashti, Mohadeseh; Reynolds, Michael R.; Rissanen, Kari; Trant, John F.; Beyeh, Ngong Kodiah (Beilstein : Institut zur Foerderung der Chemischen Wissenschaften, 2019)Single crystal X-ray structures of halogen-bonded assemblies formed between host N-hexylammonium resorcinarene bromide (1) or N-cyclohexylammonium resorcinarene chloride (2), and 1,4-diiodooctafluorobutane and accompanying ... -
Tetrameric and Dimeric [N∙∙∙I+∙∙∙N] Halogen-Bonded Supramolecular Cages
Turunen, Lotta; Peuronen, Anssi; Forsblom, Samu; Kalenius, Elina; Lahtinen, Manu; Rissanen, Kari (Wiley - VCH Verlag GmbH & Co. KGaA, 2017)Tripodal N‐donor ligands are used to form halogen‐bonded assemblies via structurally analogous Ag+‐complexes. Selective formation of discrete tetrameric I6L4 and dimeric I3L2 halonium cages, wherein multiple [N⋅⋅⋅I+⋅⋅⋅N] ... -
Concerted Halogen-Bonded Networks with N-Alkyl Ammonium Resorcinarene Bromides: From Dimeric Dumbbell to Capsular Architectures
Pan, Fangfang; Beyeh, Ngong Kodiah; Rissanen, Kari (American Chemical Society, 2015)N-Alkyl ammonium resorcinarene bromides and 1,4-diiodooctafluorobutane via multiple intermolecular halogen bonds (XB) form different exotic supramolecular architectures through subtle changes of the upper rim substituents. ...
