摘要: New planar binuclear phthalocyanines sharing the benzene ring were synthesized and their spectral properties were studied. Intense absorption in the near-IR region (850 nm) was observed for the first time.关键词: phthalocyanines zinc complexes magnesium complexes electronic absorption spectra ...
tert-Amylbenzene, with the chemical formula C11H16 and CAS registry number 2049-95-8, is a compound known for its applications in various industries. This colorless liquid, also referred to as 1,1-dimethylpropylbenzene, is characterized by its tert-amyl group attached to a benzene ring. ...
The basic structure of 1,2-Bis(bromomethyl)benzene consists of a benzene ring with two bromomethyl groups attached to adjacent carbon atoms. This compound is insoluble in water, but soluble in organic solvents such as ethanol and acetone. Safety information indicates that 1,2-Bis(bromomethyl)...
The splittings of the low temperature NMR spectra display association processes of the lithiumorganophosphides passing slowly on the NMR time scale relatively to the coupling constants. In solvents with high dielectric constants monomer contact ion pairs dominate. In solvents with mediate dielectric ...
