The results also show the sensitivity is enhanced for the pigments with a larger anilide ring. It is important to note that the photosensitivity is greatly increased when the coupler component changed ftom a 2-hydroxy-3-naphthanilide to a 2-hydroxy-11H-benzocarbazole-3-naphthanilide coupler. Clearly, conjugation effects favours to enhance the photosensitivity.

Since most of the large molecules containing phosphorus element have double bonds, it is necessary to consider the special structures of double bonds in order to deal with these large systems more accurately. So, based on density functional theory and electronegativity equalization principle, applying a general atom-bond electronegativity equalization method , using separated program, through regression and least-squares optimization , the parameters of atoms and bonds in molecules are determined . By these parameters , the charge distributions and the energy of some molecules containing phosphorus element, especial the fragment of DNA, RNA, are calculated . The results are quite good.
