Hemicyanine dyes are a subclass of polymethine colorants. At one end of their polymethine chain is an unsaturated heterocyclic ring possessing a nitrogen atom as would be found in a cyanine dye. However, the other end is terminated by a nitrogen atom that does not form part of an ...

The work in this study reports the design and synthesis of two dye molecules, namely TPA-S-Cy3 and MOTPE-S-Cy3, which incorporate the heptamethine cyanine structure and possess a D–π–A configuration. The "CC" double bond in TPA-S-Cy3 and MOTPE-S-Cy3 reacts via a Michael addition ...

In this work, the dithienylethene-based photochromic switch was firstly employed to regulate the photothermal conversion efficiency of a hemicyanine dye. The result showed that the dithienylethene-coating hemicyanine had an anticipated performance of photo-controlling photothermal conversion. The ...
Hemicyanine dyeTi O2)nclusterElectron transferWe used first- principles calculations to investigate the photo- induced electron transfer(PIET)process of the hemicyanine-(Ti O2)ncomplex((Ti O2)n-dye) for n=5, 9, 15. The geometries of the(Ti O2)n-dye in the ground state were optimized ...
