An ionic liquid (IL) composed of 9–anthracene carboxylate anion and ammonium cation possessing three diethylene glycol chains shows photo–triggered dimerization of anthracence chromophores. It causes segregation and crystallization of protonated 9–anthracene carboxylic acid dimer, which is associated with the concurrent liberation of the free amine in the IL. This work provides a new molecular design for photoresponsive ILs, whose first application for site–selective photo–patterning is demonstrated.

CO2 capture with liquid amine scrubbing has received current acceptance, however, the energy intensive heating process in CO2 recovery has to look for an alternate effective CO2 separation methods. Condensation of CO2-trapping solutions by electrodialysis and successive CO2 recoverly under reduced pressure would decrease the required energy in the CO2 capture drastically. Energy calculations and basic experiments reveal that the required energy can be reduced to less than 2.0 GJ/t-CO2, which is about a half of the energy with aqueous monoethanol amine.
