Investigating nano-structured domains within ionic liquids: the effect of cation change on thermal equilibrium and relaxation of spiropyran and spirooxazine. [PDF]

, 2009
The established belief that ionic liquids (ILs) behave as homogenous solvents such as that observed in molecular solvents has been challenged.1, 2 Previous use of solvatochromic probe dyes has allowed for the traditional parameter of ‘polarity’ to be ...

Ionogel-based light-actuated valves for controlling liquid flow in micro-fluidic manifolds [PDF]

, 2010
We present the fabrication, characterisation and performance of four novel ionic liquid polymer gels (ionogels) as photo-actuated valves incorporated into micro-fluidic manifolds. The ionogels incorporate benzospiropyran units and phosphonium-based ionic

Effect of substituted β-cyclodextrins on the kinetics of the photochromic processes and hydrolysis of trans-merocyanine

Carbohydrate Polymer Technologies and Applications
The effect of β-cyclodextrin (βCD) and its 2-hydroxypropyl, sulfate, and sulfobutyl derivatives was studied to reveal how the host-guest binding influenced the reversible photochromic reactions and the hydrolysis of a trans-merocyanine (trans-MC) dye in ...

Electrochromic properties of spiropyran-terthiophene adaptive polymers [PDF]

, 2010
Adaptive materials have the ability to modify their behaviour or characteristics in response to external stimuli, for example through electrochemical changes, macroscopically in the molecular structure. These materials may have only one form with binding
