Exploring the Synthesis of Metalloporphyrin Equipped Pd12L24 Supramolecular Spheres

Chemistry – A European Journal, EarlyView.
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

Chemistry – A European Journal, EarlyView.
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 ...

Highly Polarized 1,4‐Dihydropyrrolo[3,2‐b]Pyrroles: From Synthesis to Photophysics and Two‐Photon Induced Polymerization

Chemistry – A European Journal, EarlyView.
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 ...

Ullmann‐Type N‐Heteroarylation of Nitrogen Heterocycles Catalyzed by Heterogeneous CuNPs/HKUST‐1

EcoEnergy, EarlyView.
A practical strategy for the direct synthesis of CuNPs/HKUST‐1 heterogeneous catalyst was developed and used for the catalyzing Ullmann‐type N‐arylation of N‐heterocycles with high yields, excellent recyclability, and low copper leaching. ABSTRACT Ullmann‐type C–N coupling is an essential reaction to construct functional nitrogen heterocycles, whereas ...
