Title : Porphyrin based nanomaterials

Abstract:

Porphyrins are terapyrrolic compounds that are usually synthesized by the condensation of aromatic aldehyde with pyrrole or the reaction of dipyrromethene with an aromatic aldehyde followed by oxidation with p-chloranil. Because of its highly conjugated nature and rich 22 ? electron system, excellent chemical and physical properties, they have been used as versatile building blocks for the synthesis of nanomaterials with varying applicability, extreme molar absorption to near-infrared spectrum from the visible region, supreme oxygen quantum yields with singlet state, and chemical flexibility. Functionalized porphyrin-based nanocomposites offers various tunability modes in terms of optical, electronic, and magnetic properties and provide an efficient sensing platform to detect various analytes in the field of environment, health, and food. Porphyrin carbon nanocomposites can be used as nanosensors for the detection of toxic compounds and volatile organic compounds ( VOCs) generated during the deterioration of food. Porphyrins have demonstrated great potentials in visible-light photocatalytic applications, because of their electrical, optical and catalytic properties. This has found diverse application in the synthesis of selective nanomaterials with porphyrin like properties.  The nanoparticles of porphyrin and its derivatives have been developed for drug delivery systems which are one of the popular fields in pharmaceutical chemistry. Porphyrin nanomaterials condensing to different drug delivery variables have been utilized to enhance delivery features due to the properties that allow immune tolerance, specific targeting, better hydrophilicity, and lengthy tissue lifetime.
