  We demonstrate here the ordering of block copolymer micelles by ice
templating, below 0 {\deg}C. We used this for the preparation of silica
monoliths that present an ice-templated macroporosity, combined with a 2D
hexagonal mesostructure templated by the addition of P123. We propose a
mechanism triggered by the progressive freezing-induced concentration.
