Pyrrole Compounds as Food Mutagens
The mutagenicity of some pyrrole compounds were studied. Pyrrole compounds tested showed the mutagenicity on bacterial tester strains. Pyrrole and N-methylpyrrole had positive mutagenic activity on the ret-assay with Bacillus subtilis strains H 17 (Ret+)

Captured in water. A tetrasulfonated deep‐cavity calix[4]arene encapsulates linear and cyclic alkanes, as well as benzene and hexafluorobenzene, in water by forming a self‐assembled dimeric capsule. The binding affinity is guest size‐dependent. For linear alkanes, the affinity peaks at n‐hexane, while cyclooctane is the most strongly bound cycloalkane.

We propose a novel displacement‐assisted approach for temperature‐programmed desorption (TPD), allowing for the detection of reactive intermediates of on‐surface reactions. We demonstrate the approach by investigating the temperature‐dependent ring fusion reactions (cyclodehydrogenations) of tetraphenylporphyrin on Cu(111), revealing the quantitative ...

Synthesis and Characterization of Hemiindigo‐Based Glycoside and Glycomacrocycle
Glycosyl hemiindigos: we have synthesized hemiindigo‐functionalized glycoside and glycomacrocycle which are photoswitchable under visible light irradiation with high photoconversion yield and fluorescence emission property in acetonitrile. The conformational constrained glycomacrocycle displayed more efficient photoisomerization.

Exploring the Synthesis of Metalloporphyrin Equipped Pd12L24 Supramolecular Spheres
We expand the scope of Pd12L24 nanospheres equipped with porphyrins. Focusing on the porphyrin metallation state, synthetic strategies for porphyrin building block (BB)compounds are developed. The compounds are evaluated against nanosphere self‐assembly conditions.

Peroullazines: Synthesis, Structure, and Optoelectronic Properties
Peroullazines, longitudinally π‐extended ullazines featuring a peropyrene‐sized framework, are more electron‐rich than the corresponding peropyrene systems and exhibit optical gaps approaching those of teropyrenes. Regioselective pyridinic nitrogen incorporation further enables frontier‐orbital‐controlled tuning of their optoelectronic properties ...

Quadrupolar, centrosymmetric 1,4‐dihydropyrrolo[3,2‐b]pyrroles (DHPP) possessing two five‐membered rings and highly polarized architecture are not emissive, but they are good photosensitizers in two‐photon induced polymerization. ABSTRACT A series of ladder‐type, highly polarized functional dyes possessing 1,4‐dihydropyrrolo[3,2‐b]pyrrole (DHPP ...
