文摘

Six new dyes with “asymmetric” butterfly structure are computationally designed. Interfacial properties between the dye and TiO2 clusters are explored. The influence of nature and extent of π-linker is similar for all studied dyes. Two phenyl groups are more favorable to be used as π group in the right “wing”.
