NOVELTY - Gallium porphyrin axially functionalized graphene oxide multi-element nano hybrid material is claimed. The multi-element nano hybrid material is made of GaClTPP (I) and/or GaClTTP (II) covalently connected to modify graphene oxide (III) and the multi-element nano hybrid material is GaTPP-GO (IV), GaTTP-GO (V) or GaTPP-GO-GaTTP (VI); (I) is a 5,10,15,20-tetraphenylgallium porphyrin complex and (II) is a 5,10,15,20-tetra(2-thiophene)-based gallium porphyrin complex. USE - (VI) is useful in nonlinear optical materials and optical limiting and optical switch (all claimed). ADVANTAGE - The multielement nano hybrid material: shows excellent NLO and OL response at 532 nm, where the non-linear optical response capability of the GaTPP-GO GaTTP is good.
