A strategy for the synthesis of bacteriochlorophyll a relies on joining AD and BC halves that
contain the requisite stereochemical configurations of the target macrocycle. The BC half (1) …

Abstract SeO 2/ZnO (1, 3, 5%) nanopowders were synthesized by a sonication-assisted sol–
gel method for the first time. They were characterized by spectroscopic, morphological, and …

A route under development for the synthesis of bacteriochlorophyll a and analogues relies
on joining an AD-dihydrodipyrrin (bearing a D-ring carboxaldehyde) and a BC …

Expansion of the operational capacity of soft-Lewis basic complexant scaffolds towards
improved physical properties for the chemoselective sequestration of minor actinides from …

ortho-Quinone methides (o-QMs) underwent formal [4+ 2]-cycloaddition reactions with
arylallenes regioselectively at the styrenyl olefin to furnish the corresponding 3-methylene-2 …

The recent discovery of highly conductive, solution‐processable, n‐doped poly
(benzodifurandione)(n‐PBDF) marks a milestone in the development of conducting …

The monoanionic tetrapyrrolic macrocycle B, C-tetradehydrocorrin (TDC) resides chemically
between corroles and corrins. This chemical space remains largely unexplored due to a lack …

Natural organic matter (NOM) plays a critical role in the mobilization and bioavailability of
metals and metalloids in the aquatic environment. Selenium (Se), an environmental …

Challenges to the de novo synthesis of bacteriochlorophyll a (BChl a), the chief pigment for
anoxygenic bacterial photosynthesis, include creating the macrocycle along with the trans …
