Highly hydrophilic fused aggregates (micro sponges) from a C12 spermine bolaamphiphile
Article Abstract:
12G1, 1,10-[N, N-bis (3-aminopropyl)-1,4-butane diamine] decane (10G1), 1,8-[N, N-bis (3-aminopropyl)-1,4-butane diamine] octane (8G1), and 1-[N, N-bis (3-aminopropyl)-1,4-butane diamine] dodecane (12G0) are synthesized and there self-assembly are studied. It was found that while no aggregation in the aqueous media was recorded for either 10G1 or 8G1 up to a concentration of 20mM, aggregation of 12G1 molecules was seen to take place at an aqueous concentration of 1.75 mM as determined using various fluorescent and calorimetric probes and surface tension measurements.

Partial thermal dethreading of [3]pseudorotaxanes of alpha-cyclodextrin with linear aliphatic alpha,omega-amino acids in aqueous solution
Article Abstract:
High-precision differential scanning calorimetry (DSC) and nuclear magnetic resonance (NMR) spectroscopy were employed for investigating the partial dethreading of stable host/guest, 2:1 [3]pseudorotaxanes of (alpha)-cyclodextrine with 12-aminododecanoic acid in aqueous solutions. It was seen that the partial dethreading process that was observed, was not reversible and was reproducible after recrystallization of the 2:1 complex.

Keto forms of salicylaldehyde Schiff bases: Structural and theoretical aspects
Article Abstract:
Schiff bases of methoxy-substituted salicylaldehyde are examined by crystallographic and spectroscopic methods, as well as by density functional theory (DFT) calculations in order to investigate the effect of the substituent's position on the keto-enol in the crystalline state. The DFT calculations have presented a plausible hypothesis for the stabilization of the keto form in the crystalline state.
