Here we report the first photochromism of a newly designed [2.2]paracyclophane-bridged imidazole dimer in water. The photochromic dye with a hydrophilic and a hydrophobic substituent forms vesicles in water and shows instantaneous colouration upon UV light irradiation and successive rapid fading in the dark.
Disclosed are a carrier for use for separation purpose and a method for separation of a compound which enable a chemical reaction to be performed in a liquid phase, enable a compound of interest to be separated from the liquid phase after the completion of the reaction readily, enable the separated compound to be evaluated by structural analysis or the like while the compound being bound to the carrier, and enable the compound to be separated from the carrier readily. A carrier for separation which has a reaction site capable of reacting with other compound on a benzene ring, and a long-chain group having a specified carbon atom(s) at each of the ortho-position and the para-position of the reaction site through an oxygen atom.

2-bromodecanoic acid. Six structures of lanthanide complexes with 2,6-bis(benzoxazol-2-yl)pyridine L6 were then determined to evaluate the types of species that are likely to be involved in the separation process. Three structural types were observed, namely [LnL6(NO3)3(H2O)2], 11-coordinate only for La, [LnL6(NO3)3 (CH3CN)], 10-coordinate for Pr, Nd and Eu and [LnL6(NO3)3(H2O)], L 10-coordinate for Eu
