I have prepared some derivatives of the Copper 8-Hydroxyquinoline complex. It has very low solubility in the DMSO, DMF, and CDCl3. In such a scenario, having a paramagnetic Cu2+ in the structure, How to record an NMR spectrum of the Copper 8-Hydroxyquinoline complex and its derivatives?
Dear Prasad,
Cu2+ usually increase T1 relaxation but not really T2 relaxation (which would be bad). This means you can reduce the D1 delay to reduce measurementtime. Otherwise it should be fine to record 1H experiments, but no garantee. to determine the T1 relaxation and teherefore the d1 delay time you can use the parameterset 1HsatrecT1. after recording you can click on "Applications->Dynamics->Prepare for Dynamics Center" and than again at the same button Saying "Dynamics Center" and the result should pop up. If you have installed the free of charge Bruker Dynamics Center on yur computer.
Many Greetings,
Kristof
