Alignment of pyrene aromatics along RNA double helix.
Multiple pyrene modified RNA duplex exhibits pyrene excimer fluorescence. The pyrene excimer fluorescence is significantly enhanced with an increase in the number of incorporated pyrenes. The pyrenes in the RNA helically aggregate with partial pi-stacking along outside of double stranded helical backbone.
