Solid-supported Zn(II) porphyrin tweezers as optical sensors for diamines.
A melamine-bridged bis-Zn(II) porphyrin dyad covalently attached onto amino-functionalized TentaGel polymer beads or controlled pore glass (CPG) undergoes a reversible and marked colour change from purple to green upon exposure to a biogenic diamine such as cadaverine both in organic and aqueous media.
