Cyclomaltooligosaccharide (cyclodextrin)-assisted enantiomeric recognition of benzo[lmn][3,8]phenanthroline-derived amino acids
Jursic, Branko S.,Patel, Paresh K.
, p. 1413 - 1418 (2005)
Formation of self-assembly molecular aggregates and cyclomaltooligosaccharide (cyclodextrin) molecular aggregates with benzo[lmn][3,8]phenanthroline-derived amino acids is presented. The nature of the molecular aggregates was studied by negative-ion elect

Metal–organic polyhedra (MOP) are a promising class of crystalline porous materials with multifarious potential applications. Although MOPs and metal–organic frameworks (MOFs) have similar potential in terms of their intrinsic porosities and physicochemical properties, the exploitation of carboxylate MOPs is still rudimentary because of the lack of systematic development addressing their chemical stability. Herein we describe the fabrication of chemically robust carboxylate MOPs via outer-surface functionalization as an a priori methodology, to stabilize those MOPs system where metal–ligand bond is not so strong. Fine-tuning of hydrophobic shielding is key to attaining chemical inertness with retention of the framework integrity over a wide range of pH values, in strong acidic conditions, and in oxidizing and reducing media. These results are further corroborated by molecular modelling studies. Owing to the unprecedented transition from instability to a chemically ultra-stable regime using a rapid ambient-temperature gram-scale synthesis (within seconds), a prototype strategy towards chemically stable MOPs is reported.
Efficient and mild microwave-assisted stepwise functionalization of naphthalenediimide with α-amino acids
Pengo, Paolo,Pantos, G. Dan,Otto, Sijbren,Sanders, Jeremy K. M.

The process of protein misfolding and aggregation to form neurotoxic species is strongly implicated in most of the neurodegenerative disorders. In particular, amyloid beta (Aβ) misfolding and aggregation is central to pathophysiological processes of Alzhe
Steric effect on the self-assembly behaviours of amino acid derivatives
Fan, Yulan,Cheng, Linxiu,Liu, Chunhua,Xie, Yunzhi,Liu, Wei,Li, Yongdong,Li, Xun,Li, Yibao,Fan, Xiaolin

Crystallographic insight-guided nanoarchitectonics of peptide-conjugated naphthalene diimide (NDI) is described. In a bio-inspired approach, non-proteinogenic α-amino isobutyric acid (Aib)- and alanine (Ala)-derived peptides orchestrated the 1D achiral and 2D chiral molecular ordering of NDI, respectively, which resulted in modulation of nanoscale morphology, chiroptical and conductivity properties.
Molecular assembly of amino acid interlinked, topologically symmetric, π-complementary donor-acceptor-donor triads
