Cation-pi interactions in aromatics of biological and medicinal interest: Electrostatic potential surfaces as a useful qualitative guide [PDF]

open access: yes, 1996
The cation-pi interaction is an important, general force for molecular recognition in biological receptors. Through the sidechains of aromatic amino acids, novel binding sites for cationic ligands such as acetylcholine can be constructed.

Bridging the Gap Between Traditional and Nontraditional Luminogens With Strong Non‐Aromatic Through‐Bond Conjugation and Through‐Space Conjugation

open access: yesAggregate, EarlyView.
Due to the combinational effects of strong non‐aromatic through‐bond conjugation (TBC) and through‐space conjugation (TSC), dihydropyridine derivatives exhibit photoluminescent behaviors between those of traditional luminogens (TLs) and nontraditional luminogens (NTLs), thus bridging the gap between TLs and NTLs.

Copper‐Catalyzed Synthesis of C‐2 Substituted Indolin‐3‐Ones and Indolin‐3‐One [4+2] Cycloadducts Through Azide‐Tethered Iodonium Ylides

open access: yesAsian Journal of Organic Chemistry, EarlyView.
Azide‐tethered iodonium ylides under copper catalysis generate metallocarbenes that undergo intramolecular trapping by the azide moiety and generate a reactive C‐acylimine, effectively coupling two nucleophilic centers. This intermediate can be trapped by a wide range of nucleophiles or 1,3‐dienes producing complex indolin‐3‐ones and ...

Manipulating Self-Assembly in Silver(I) Complexes of 1,3-Di-\u3cem\u3eN\u3c/em\u3e-pyrazolylorganyls [PDF]

open access: yes, 2009
Three di-N-pyrazolylorganyls with different conformational flexibilities in the three-atom organyl spacers have been prepared, and the self-assembly properties with AgBF4 have been studied both in solution and in the solid state.
