Molecular Photonics of 3,3'-diethyl-9-methylthiacarbocyanine Monomers and Dimeric Complexes with Cucurbit[8]uril

نویسندگان

چکیده

A comparative study of the spectral-luminescent and spectral-kinetic properties 3,3'-diethyl-9-methylthiacarbocyanine (MTCC) 3,3'-diethylthiacarbocyanine (TCC) their complexes with cucurbit[8]uril in aqueous solution was carried out. Dimeric TCC consist trans-isomers exhibit only delayed fluorescence while dimeric MTCC cis-isomers both phosphorescence water. The participate electron phototransfer reaction where complex exhibits a greater ability to enter into photooxidation reactions. Keywords: polymethine dyes, trans-cis isomerization, cucurbiturils, absorption, fluorescence, triplet-triplet phototransfer.

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

Copolymerization of polar monomers with olefins using transition-metal complexes.

Transition-metal catalysts long ago made it from the laboratory bench to the polymerization reactor. Indeed, they are being used around the world to make more than 70 million tons of polyethylene and polypropylene a year. Transition-metal catalysts give polyolefin producers unprecedented flexibility in process and polymer design. However, there are still new worlds for catalysts to conquer. One...
