We have successfully synthesized a novel photoactive supramolecular assembly in which a tetraphenyl-porphyrin core is decorated with four of the receptor molecule, CB7. This assembly (TPP-4CB7) has an appreciable amount of water solubility and thus, can be used in many applications due to its distinctive features including combined photo and chemotherapy, chemo-/bio-sensors and photocatalysis. In this study,we have shown its abilityas a photocatalyst in the hydrogen production from water splitting. Although TPP-4CB7 by its own acts as a visible light triggered photocatalyst, its photocatalytic activity has enhanced significantly uponforming nanocomposite with TiO2 as carbonyl portals of CB7 s act as anchoring groups and co-ordinate with TiO2 to give rise homogenous mixture. The resulting nanocomposite, TPP-CB-TiO2@Pt, is very efficient and stable photocatalyst and produces high amount of hydrogen (24.5 mmolh-1g-1, onset potential 10 mV, TOF of 0.202 s-1) without the necessity of extra sacrificial agent in alkaline media.
