Abstract: N,N'-dihydroxy-1,4,5,8-naphthalenetetracarboxdiimide (NDI-(OH)2) has attracted much attention in recent years, because its doubly deprotonated state, (O-NDI-O)2-, has metal-coordination ability and characteristic electronic transition useful for designing electronic and optical functions. In contrast, a molecular crystal with… read more here.

DOI: 10.3390/cryst9030126
Abstract: Protein crystals, otherwise usually colorless, can be stained a variety of hues by saturating them with dyes, by diffusion from the mother liquor or co-crystallization. The colors assumed by dyes are a function of chemical… read more here.
