Aromatic ring between the benzene-and quinone, forming a large conjugated system, the energy needed to reduce electronic transition, so that the absorption band red-shifted to longer wavelength;

Fang-ring somewhere between direct-style and benzoquinone style and create a great enthusiasm for a total energy system, electronic transcendence needed to reduce absorption bands, thereby moving red wave direction;

The aromatic ring is situated between between the benzene type and the quinone type, forms in a big way altogether clutches the system, the electron transition needs the energy to reduce, thus causes the absorption band to have the red shift to the long wave direction;
