This disclosure relates to conjugates for targeting bacteria and related uses. In certain embodiments, the disclosure relates to methods of transferring a molecule of interest into bacteria comprising mixing bacteria with a non-naturally occurring conjugate under conditions such that the conjugate is transported across the bacterial cell wall. Typically, the conjugate comprises an oligosaccharide and a molecule of interest. In certain embodiments, the molecule of interest may be a tracer or an antibiotic.

fluorescent probe was designed for the recognition of electron-rich salicylicacidderivatives (SAs). The imidazole-appended aminomethyl perylene probe 1 selectively differentiated between electron-rich amino-SAs and electron-deficient nitro-SAs in EtOH, exhibiting the highest selectivity and sensitivity toward 5-aminosalicylic acid (5-ASA) and showing strong 1:1 binding (Ka = 1.37 × 107 M− 1).

设计了一种新颖的简单荧光探针,用于识别富含电子的水杨酸衍生物(SAs)。咪唑附加的氨基甲基per探针1在EtOH中选择性区分富电子的氨基SA和缺电子的硝基SA,对5-氨基水杨酸(5-ASA)表现出最高的选择性和灵敏度,并表现出强大的1:1结合(K a = 1.37×10 7 M -1)。这种高的选择性和灵敏度是由于仲胺和咪唑单元的协同多个氢键相互作用以及富电子和缺电子环之间的π-π相互作用以及5-ASA与and部分之间异常的NH-π相互作用引起的共1。EtOH中5-ASA的检出限(LOD)为0.012 ppb。

The present disclosure relates to novel photoluminescent complexes comprising a BODIPY moiety covalently bonded to a blue light absorbing moiety, a color conversion film comprising the photoluminescent complex, and a back-light unit using the same.
energy/electron-transfer represents the central processes for photosynthesis. However, it's still a challenge to develop a heavy-atom-free (HAF) strategy to improve the sensitizing ability of polymeric photosensitizers. Herein, we propose a new protocol to significantly improve the photosensitization by decorating mother conjugated microporous polymer (CMP-1) with polycyclic aromatichydrocarbons (PAHs)
An efficient, one-pot methodology of direct synthesis of perylene-fused cyclicketones from perylene and 2-alkenoic acids under acidic catalytic conditions has been developed. The reaction of perylene with 2,3-disubstituted 2-alkenoic acid leads, via Friedel–Crafts acylation followed by Nazarov cyclization, to the formation of disubstituted 5,6-dihydro-4H-cyclopenta[b]perylen-4-ones in high yield (up
