Abstract

The green organic semiconductor, tris-(8-hydroxyquinoline)aluminum (Alq₃), was hybridized with DNA growing in the shape of hexagonal prismatic crystals. In this study, we applied hydrodynamic flow to the fabrication of Alq₃ crystals doped with DNA molecules. The hydrodynamic flow in the Taylor-Couette reactor induced nanoscale pores in the Alq₃ crystals, especially at the side part of the particles. The particles exhibited distinctly different photoluminescence emissions divided into three parts compared to common Alq₃-DNA hybrid crystals. We named this particle a “three-photonic-unit”. After treatment with complementary target DNA, the three-photonic-unit Alq₃ particles doped with DNAs were found to emit depressed luminescence from side parts of the particles. This novel phenomenon would expand the technological value of these hybrid crystals with divided photoluminescence emissions toward a wider range of bio-photonic applications.
