Article Abstract

We report a -quinodimethane skeleton (-QDM)-based polycyclic aromatic hydrocarbon (PAH) with heptenes as end-capping groups and F-substituents in the central six-membered ring. This compound shows the -configuration in one crystal form with relative strong emission ( = 0.25), and the -configuration in another crystal form with weak emission. Furthermore, this compound was transformed into the more annulated PAHs on-surface C-F bond activations.

Visible-light-responsive Rh/Sb co-doped SrTiO with engineered {100}/{110} facets (STO:RS(NaCl)) was synthesized flux-assisted crystallization. Facet-dependent spatial charge separation, driven by work function differences, enabled electrons and holes to migrate to the respective facets. This configuration tripled photocatalytic hydrogen evolution non-faceted STO:RS(w/o), overcoming the limitations of ultraviolet-only absorption and inefficient charge separation.

The persistent threat posed by phytopathogenic fungi to agricultural systems underscores the critical need for novel fungicides. Here, we synthesized and characterized a series of novel acridospiroisoxazole derivatives (H1-H36) using H/C NMR and mass spectrometry. The absolute configuration of compound H23 was confirmed using single-crystal x-ray diffraction analysis.
