Introduction the unique properties of graphene oxide (go) have driven research on using go in functional materials for diverse applications 1–4 go is produced by a variety of scalable methods that result in similar, but not identical, products 5 theories about the exact structure of go have continuously evolved because of the non-homogenous nature of the material 6 a commonly.
The optical limiting (ol) properties of single-layer graphene dispersions in different solvents were studied using a nanosecond pulse laser the graphene dispersions, especially in heavy-atom solvents, showed much better ol properties compared with referenced c60-toluene solution. Three kinds of graphene oxide (go)–porphyrin composites were facilely assembled by means of non-covalent interaction it was found that the functional groups linked on the peripheries of the porphyrins had an important influence on the combination mode of porphyrin and go, and also the properties of go–porphyrin composites 5, 10, 15, 20-tetrakis(4-hydroxyphenyl)porphyrin (thpp) was easy.
