These materials display a clear "Janus" like character and are able to selectively and completely separate hydrophobic dyes form a mixture of dyes. Our results clearly suggest a clear partition of more hydrophobic dyes into the pores from a mixture of two dyes. In addition this material displays a remarkable recycling ability for 10 cycles with up to similar to 99% dye removal from water.1 aShinde, Pravin1 aGupta, Sayam, Sen1 aSingh, Baljeet1 aPolshettiwar, Vivek1 aPrasad, Bhagavatula, L.
