AI Article Synopsis
- A novel fluorescent dye molecule, HPPD, self-assembles in ethanol/chloroform to form J-aggregated microribbons via π-π stacking, exhibiting optical resonance in the visible range.
- The borondifluoride variant, HPPD-BF, has a lower energy gap and forms crystalline microrods that function as an F-P type resonator in the near-infrared spectrum.
- This research highlights the potential for creating advanced dye materials with specific optical properties through self-assembly processes.
Article Abstract
A novel supramolecular fluorescent donor-acceptor type dye molecule, (2E,4E)-1-(2-hydroxyphenyl)-5-(pyren-1-yl)penta-2,4-dien-1-one (HPPD) self-assembles in a mixture of ethanol/chloroform through intermolecular π-π stacking (distance ca. 3.384 Å) to form J-aggregated single-crystalline microribbons displaying Fabry-Pèrot (F-P) type visible-range optical resonance. The corresponding borondifluoride dye (HPPD-BF), with a reduced HOMO-LUMO gap, self-assembles into crystalline microrods acting as an F-P type resonator in the near-infrared (NIR) range.
