Thixotropic organogels based on a simple N-hydroxyalkyl amide: rheological and aging properties.
The thixotropic properties ofthermoreversible organogels composed ofN-3-hydroxypropyl dodecanamide and various apolar fluids have been investigated by X-ray scattering, light microscopy, andExpand
Structural Aspects of the Gelation Process Observed with Low Molecular Mass Organogelators
We present an experimental study of the mechanism of formation and the mechanical properties of an organogel, formed by the gelator compound 2,3-di-n-decyloxyanthracene (DDOA) in propylene carbonate.Expand
Theoretical investigation of the dynamic first hyperpolarizability of DHA–VHF molecular switches
The contrast of second-order nonlinear optical response in the dihydroazulene (DHA)-vinylheptafulvene (VHF) equilibrium has been investigated as a function of the nature of the substituent (R) on theExpand
Synthesis and Photochromic Behaviour of Naphthopyrans, Pyranoquinolines, Pyranoquinazolines and Pyranoquinoxalines
New chromenes annulated with different six-membered azaheterocycles were prepared, i.e., the 3H-pyra-no[3,2-f]quinolines 9/10 and 14, the 8H-pyrano[2,3-h]isoquinoline 11, theExpand
Furo-fused 2H-chromenes: synthesis and photochromic properties
New photochromic chromenes annulated with a furan ring have been synthesized. Thus, suitable heterocyclic phenols react with different propargylic alcohols in acidic medium to give the correspondingExpand
Toward multi-addressable molecular systems: Efficient synthesis and photochromic performance of unsymmetrical bisthienylethenes
Abstract Various synthetic routes have been compared to access to unsymmetrical 1,2-bisthienylperfluorocyclopentenes having one electro-withdrawing formyl group. The strategy based on keyExpand
Synthesis of photochromic 6-aryl-substituted bis(benzothiophenyl)- perfluorocyclopentenes by the Suzuki–Miyaura cross-coupling
The Suzuki cross-coupling of 1,2-bis(6-iodo-2-methylbenzo[b]thiophen-3-yl)hexafluorocyclopentene and (het)arylboronic acids depending on the reaction conditions affords bis- or mono-adducts. TheExpand
Design and characterization of molecular nonlinear optical switches.
The rational design of molecular NLO switches, which combines experimental and theoretical approaches, has reached maturity, and a critical overview of the different theoretical approaches used for evaluating the first hyperpolarizabilities is provided. Expand
Nonlinear optical molecular switches as selective cation sensors.
This work demonstrates that the recognition of cations by molecular switches can give rise to large contrasts of the second-order nonlinear optical (NLO) properties, which can therefore be used as aExpand
