Substituted nitrogen-bridged diazocines [PDF]
Beilstein Journal of Organic Chemistry, 2021 Novel nitrogen-bridged diazocines (triazocines) were synthesized that carry a formyl or an acetyl group at the CH2NR-bridge and bromo- or iodo-substituents at the distant phenyl ring.

Synthesis of N-acetyl diazocine derivatives via cross-coupling reaction [PDF]
Beilstein Journal of Organic ChemistryDiazocines are photoswitches derived from azobenzenes by bridging the two phenyl rings in ortho position with a CH2CH2 group forming an eight membered (diazocine) ring.

Light-Powered Dissipative Assembly of Diazocine Coordination Cages. [PDF]
J Am Chem Soc, 2022 Stimuli-responsive coordination cages allow reversible control over guest binding and release, relevant for adaptive receptors, carriers, catalysts, and complex systems. Light serves as an advantageous stimulus, as it can be applied with precise spatial and temporal resolution without producing chemical waste products.

Unsymmetrically Substituted Dibenzo[b,f][1,5]-diazocine-6,12(5H,11H)dione—A Convenient Scaffold for Bioactive Molecule Design [PDF]
Molecules, 2020 A novel approach for the synthesis of unsymmetrically substituted dibenzo[b,f][1,5]diazocine-6,12(5H,11H)diones has been developed. This facile three-step method uses variously substituted 1H-benzo[d][1,3]oxazine-2,4-diones (isatoic anhydrides) and 2 ...

Facile Synthesis of Light-Switchable Polymers with Diazocine Units in the Main Chain. [PDF]
Polymers (Basel), 2023 Unlike azobenzene, the photoisomerization behavior of its ethylene-bridged derivative, diazocine, has hardly been explored in synthetic polymers. In this communication, linear photoresponsive poly(thioether)s containing diazocine moieties in the polymer ...

Diazocine-functionalized TATA platforms [PDF]
Beilstein Journal of Organic Chemistry, 2019 Recently, it has been shown that the thermochemical cis→trans isomerization of azobenzenes is accelerated by a factor of more than 1000 by electronic coupling to a gold surface via a conjugated system with 11 bonds and a distance of 14 Å.

Triplet sensitization enables bidirectional isomerization of diazocine with 130 nm redshift in excitation wavelengths. [PDF]
Chem Sci, 2023 Diazocines are bridged azobenzenes with phenyl rings connected by a CH2–CH2 group. Despite this rather small structural difference, diazocine exhibits improved properties over azobenzene as a photoswitch and most importantly, its Z configuration is more ...
