Substituted nitrogen-bridged diazocines. [PDF]

open access: yesBeilstein J Org Chem, 2021
Novel nitrogen-bridged diazocines (triazocines) were synthesized that carry a formyl or an acetyl group at the CH 2 NR-bridge and bromo- or iodo-substituents at the distant phenyl ring. The photophysical properties were investigated in acetonitrile and water.

Photoswitching Lanthanoid Luminescence With Diazocines. [PDF]

open access: yesChemistry
AbstractThe unique photophysical properties of the lanthanoids provide the core functionality for various high‐tech applications, including optoelectronic materials, lasers, anti‐counterfeiting dyes, or tools for biological sciences. The combination of these luminophores with photoswitches has the potential to make them remote controllable and adds new

Light-Powered Dissipative Assembly of Diazocine Coordination Cages. [PDF]

open access: yesJ 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.

Diazocine-functionalized TATA platforms [PDF]

open access: yesBeilstein 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.

Photoswitching of Diazocines in Aqueous Media

open access: yesThe Journal of Organic Chemistry, 2021
We present a systematic investigation of the photophysical properties of diazocines in aqueous media. The Z-E photoconversion yields of CH2CH2- and CH2S-bridged diazocines decrease with increasing water content in acetonitrile. However, there is one exception.

Reproductive Mechanisms Influenced by a Diazocine

open access: yesExperimental Biology and Medicine, 1965
Summary2,8-Dichloro-6,12-diphenyl-dibenzo[b,f][l,5] diazocine completely inhibited pregnancy when administered either orally or subcutaneously to female rats at doses as low as 0.5 mg daily for 7 days at time of mating. At higher doses, single treatments prior to completion of implantation were equally effective.

Amino-substituted diazocines as pincer-type photochromic switches [PDF]

open access: yesBeilstein Journal of Organic Chemistry, 2013
Azobenzenes are robust, reliable, and easy to synthesize photochromic switches. However, their high conformational flexibility is a disadvantage in machine-like applications. The almost free rotation of the phenyl groups can be restricted by bridging two ortho positions with a CH2CH2 group, as realized in the dihydrodibenzo diazocine framework.

The Pyrolysis of 1,2,3,4,6,7-Hexathia-5,8-diazocine [PDF]

open access: yesBulletin of the Chemical Society of Japan, 1990
Abstract Crystals of 1,2,3,4,6,7-hexathia-5,8-diazocine (1,4-S6(NH)2) were transformed around 363 K with a molar enthalpy change of the transformation of 2.40±0.07 kJ mol−1. Crystal systems of the two forms of 1,4-S6(NH)2 were identified to be orthorhombic (α-form) and monoclinic (β-form) below and above this temperature.
