A Halogen-Bond Donor Catalyst for Templated Macrocyclization

, 2019
International audienceA halogen-bond templated 11 macrocyclization in solution is reported. Tetra(iodoperfluorophenyl) ethers were used as halogen-bonded exotemplates in a substoichiometric amount (5 mol %).

Halogen-Bond-Controlled Self-Assembly of Regioisomeric Phenanthridine Derivatives into Nanowires and Nanosheets

, 2020
The spectroscopic and photophysical properties of organic materials in the films are widely influenced by their molecular packing morphologies and intermolecular interactions. Here, regioisomeric phenanthridine derivatives were synthesized.

Multidentate Iodoalkyne Receptors as Halogen Bond Donors [PDF]

, 2015
Halogen bonding is an expanding area in supramolecular chemistry. Previously, the Taylor group has reported a series of multidentate iodoperfluoroarene based receptors that displayed strong halogen bonding with anions in solution.

Effect of Fast Curing Lights, Argon Laser, and Plasma Arc on Bond Strengths of Orthodontic Brackets: An In Vitro Study

Frontiers in Dentistry, 2008
Objective: Nowadays light-cured composites are used widely by orthodontists to bond brackets. As these composites require 20-40 seconds time per tooth to be light cured, more chair-time in needed compared to self-cured composites.
