Abstract: We report the first X-ray study on monodomains of the recently discovered blue phases with presumed smectic order. We have succeeded in growing large, well oriented monodomains of BP2. X-ray scattering performed on these monodomains clearly show that smectic order is present in these blue phases but with a smaller correlation length than in the neighbouring TGB phase. Moreover the smectic order possesses the symmetry of the blue phase lattice.
