Preferential solvation of 1,4-dihydroxy-3-methylanthracene-9,10-dione (DHMAD) has been investigated using optical absorption and fluorescence emission techniques. Optical absorption spectra of DHMAD in different solvents show the intra molecular charge transfer band in the region 400-550 nm. The preferential solvation parameter shows that in dimethyl formamide (DMF)+carbon tetrachloride (CCl(4)) mixture, the DHMAD is preferentially solvated by DMF in the ground state and in the excited state DHMAD is preferentially solvated by CCl(4) in DMF rich region and by DMF in CCl(4) rich region.
使用光学吸收和荧光发射技术研究了 1,4-二羟基-3-甲基蒽-9,10-二酮（DHMAD）的优先溶剂化作用。DHMAD 在不同溶剂中的光学吸收光谱在 400-550nm 区域显示出分子内电荷转移带。优先溶剂化参数表明，在二甲基甲酰胺（DMF）+四氯化碳（CCl4）混合物中，DHMAD 在基态优先被 DMF 溶剂化，而在激发态，DHMAD 在 DMF 丰富的区域优先被 CCl4 溶剂化，在 CCl4 丰富的区域优先被 DMF 溶剂化。
