PH-Tunable Fluorescence and Photochromism of a Flavylium-Based MCM-41 Pigment.

ABSTRACT: Incorporation of flavylium-derived chalcones in the cetyltrimethylammonium bromide-templated synthesis of mesoporous silica particles with no subsequent removal of the micellar phase leads to high luminescence (0.3 < ϕ_f < 0.5) and strong color-contrast photochromic pigments finely tunable over a large pH range (1 < pH < 11).
