The incorporation of a chiral porphyrin into the mesoporous molecular sieves SBA‐15 by reactions of the surface OH group with an amino group of the porphyrin and its chiral recognition were studied. The resultant material was analyzed by a combination of techniques and it was confirmed that the channels of SBA‐15 have been filled with chiral porphyrins, leaving the mesopores unaffected. The investigation of chiral recognition of the porphyrin and the composite SBA‐15 shows that the incorporated SBA‐15 has a clear CD spectral signal of the chiral porphyrin and exhibits different chiral recognition abilities for small amino acids. The D ‐alanine is more tightly bound to the mesoporous composite SBA‐15 than its optical antipode. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
