抄録

Naphthalenediimide (NDI) is generally a yellowish to reddish chromophore, which shows vapochromism by the alternation of charge-transfer (CT) interactions at the NDI core. On the contrary, we discovered that the deprotonation of N,N - dihydroxy-1,4,5,8-naphthalenetetracarboxdiimide (NDI-(OH)2) gave a bluish organic salt with a hydrochromic property, which has been rare in conventional NDI derivatives. On the basis of the structural analyses and the calculation, the origin of the hydrochromism can be explained by the change of hydrogenbond interaction between the anionic imide group and H2O molecules.
