• 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. ...

• Bamboo-like Chained Cavities and Other Halogen-Bonded Complexes from Tetrahaloethynyl Cavitands with Simple Ditopic Halogen Bond Acceptors 

  Turunen, Lotta; Pan, FangFang; Beyeh, Ngong Kodiah; Trant, John F.; Ras, Robin H. A.; Rissanen, Kari (American Chemical Society, 2018)

  Halogen bonding provides a useful complement to hydrogen bonding and metal-coordination as a tool for organizing supramolecular systems. Resorcinarenes, tetrameric bowl-shaped cavitands, have been previously shown to ...

• The Recognition of Viologen Derivatives in Water by N-Alkyl Ammonium Resorcinarene Chlorides 

  Beyeh, Ngong Kodiah; Jo, Hyun Hwa; Kolesnichenko, Igor; Pan, FangFang; Kalenius, Elina; Anslyn, Eric Van; Ras, Robin H. A.; Rissanen, Kari (American Chemical Society, 2017)

  Three water-soluble N-alkyl ammonium resorcinarene chlorides decorated with terminal hydroxyl groups at the lower rims were synthesized and characterized. The receptors were decorated at the upper rim with either terminal ...

• Halogen-Bonded Mono-, Di-, and Tritopic N-Alkyl-3-iodopyridinium Salts 

  Rautiainen, J. Mikko; Green, Maryna; Mähönen, Minna; Moilanen, Jani O.; Lahtinen, Manu; Valkonen, Arto (American Chemical Society (ACS), 2023)

  Halogen bonding interactions of 15 crystalline 3-iodopyridinium systems were investigated. These systems were derived from four N-alkylated 3-iodopyridinium salts prepared in this study. The experimental results in the ...

• Halogen-Bonded Co-Crystals of Aromatic N-oxides : Polydentate Acceptors for Halogen and Hydrogen Bonds 

  Puttreddy, Rakesh; Topic, Filip; Valkonen, Arto; Rissanen, Kari (MDPI AG, 2017)

  The C-ethyl-2-methylresorcinarene (1) forms 1:1 in-cavity complexes with aromatic N,N′-dioxides, only if each of the aromatic rings has an N−O group. The structurally different C-shaped 2,2′-bipyridine N,N′-dioxide ...
