Abstract

Licht‐Aquädukt: Periodische mesoporöse Organosilicate absorbieren wegen der dichtgepackten organischen Chromophore in den Porenwänden Licht sehr stark. Die durch 125 Biphenylgruppen in den Porenwänden absorbierte Lichtenergie wird mit fast 100 % Quantenausbeute zu einem einzigen Cumarin‐1‐Molekül in den Mesokanälen geleitet, was eine signifikante Erhöhung der Emission des Cumarin‐1‐Farbstoffs zur Folge hat.magnified image

## Abstract **Summary:** A new calix[4]arene‐based periodic mesoporous organosilica has been synthesized using tetraethoxysilane (TEOS) and a calix[4]arene‐based silane monomer as the precursors and cetyltrimethylammonium bromide (CTAB) surfactant as the structure‐directing template, and is shown t
