1-Iodonaphthalene(cas: 90-14-2) is one of organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles.Quality Control of 1-Iodonaphthalene

Quality Control of 1-IodonaphthaleneIn 2021 ,《Single-molecule junction formation in break-junction measurements》 was published in Journal of Physical Chemistry Letters. The article was written by Fu, Tianren; Frommer, Kathleen; Nuckolls, Colin; Venkataraman, Latha. The article contains the following contents:

The scanning tunneling microscope-based break-junction (STM-BJ) technique is the most common method used to study the electronic properties of single-mol. junctions. It relies on repeatedly forming and rupturing a Au contact in an environment of the target mols. The probability of junction formation is typically very high (∼70-95%), prompting questions relating to how the nanoscale structure of the Au electrode before the metal point contact ruptures alters junction formation. Here we analyze conductance traces measured with the STM-BJ setup by combining correlation anal. and multiple machine learning tools, including gradient-boosted trees and neural networks. We show that two key features describing the Au-Au contact prior to rupture determine the extent of contact relaxation (snapback) and the probability of junction formation. Importantly, our data strongly indicate that mol. junctions are formed prior to the rupture of the Au-Au contact, explaining the high probability of junction formation observed in room-temperature solution measurements. The results came from multiple reactions, including the reaction of 1-Iodonaphthalene(cas: 90-14-2Quality Control of 1-Iodonaphthalene)
