Breakdown of the mirror image symmetry in the optical absorption/emission spectra of oligo(para-phenylene)s [PDF]
, 2005 The absorption and emission spectra of most luminescent, pi-conjugated, organic molecules are the mirror image of each other. In some cases, however, this symmetry is severely broken.

Advanced Optical Materials, EarlyView.Intramolecular bridge‐locking frustrates detrimental anti‐parallel packing in evaporated organic films. This design enhances net polar orientation, leading to a twofold off‐resonance increase in the second‐order nonlinear susceptibility (χ(2)) without electric‐field poling.

Advanced Science, EarlyView.Cinnamic‐hydroxamic‐acid derivatives (CHADs) are identified as novel inhibitors of the bacterial nucleoid‐associated protein HU, exhibiting potent antibacterial, anti‐biofilm (both inhibition and eradication), and DNA relaxation (anti‐supercoiling) activities. Moreover, CHADs demonstrate strong synergistic effects with multiple antibiotics.

Acta Crystallographica Section E Structure Reports Online, 2008 The mol-ecule of the title compound, C(17)H(10)O, is nearly planar, the largest deviation from the mean plane being 0.06 Å. The crystal structure is governed by π-π inter-actions, with centroid-centroid distances ranging from .559 to 3.730 Å.

Advanced Science, EarlyView.A series of through‐space coupled donor‐acceptor (D–A) molecules is sandwiched between two electrodes to determine their single‐molecule conductance. As the D–A interaction weakens, single‐molecule conductance reduces while Flicker Noise PSD n‐value increases (coupling strength decreases).
