4-(4-Propoxybenzoyloxy)benzoic acid [PDF]

Acta Crystallographica Section E Structure Reports Online, 2008
The title compound, C(17)H(16)O(5), is an important inter-mediate for the synthesis of side-chain ligands for polymeric liquid crystals. The prop-oxy and benzoic acid groups subtend dihedral angles of 4.36 (6) and 55.35 (6)°, respectively, with the central benzo-yloxy unit. The crystal structure is stabilized by an inter-molecular O-H⋯O hydrogen bond.

3,5-Bis(benzyloxy)benzoic acid [PDF]

Acta Crystallographica Section E Structure Reports Online, 2012
In the title compound, C(21)H(18)O(4), the outer benzyl rings are disordered over two resolved positions in a 0.50 ratio. The O-CH(2) groups form dihedral angles of 4.1 (2) and 10.9 (4)° with the central benzene ring, adopting a syn-anti conformation with respect to this ring. In the crystal, the mol-ecules are linked by O-H⋯O hydrogen bonds and weak C-

Controlled Aggregation of Pyrene‐Based Supramolecular Nanostructures for Light‐Driven Switchable H2 or H2O2 Production

Advanced Functional Materials, EarlyView.
This work reports the self‐assembly of a pyrene derivative into two distinct nanostructures and their application in visible‐light photocatalysis. The two nanostructures exhibit completely different yet complementary photocatalytic activities, promoting either H2 or H2O2 evolution.

Modulating Two‐Photon Absorption in a Pyrene‐Based MOF Series: An In‐Depth Investigation of Structure–Property Relationships

Advanced Functional Materials, EarlyView.
This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.
