Photostabilization of J-aggregate cyanine dyes for exciton-polariton based devices
… Using J-aggregates, the aggregated form of cyanine organic dyes, we have previously fabricated light-emitting devices that demonstrated the first ever electrically pumped polariton emission, as well as critically coupled resonators with record high effective absorption constants. Although …

Exploring the Influence of structural variation on the solution and solid-state behaviour of cyanine
Cyanine dyes are well known and extensively studied molecules. The preparations and investigations of a wide range of dyes have been previously reported. Here several novel and known compounds have been synthesised to investigate the effect molecular structure has on their bulk-solution and …

Nanocrystal/J-aggregate constructs : chemistry, energy transfer, and applications
… semiconductor nanocrystals and J-aggregates of cyanine dyes, have been developed chiefly due to their potential for interacting with light in interesting and productive ways. At the same time, existing spectroscopy and microscopy tools enable the study of these photonic materials, their …

Solid state cavity QED : practical applications of strong coupling of light and matter
J-aggregates of cyanine dyes are the excitonic materials of choice for realizing polariton devices that operate in strong coupling at room temperature. Since the earliest days of cavity QED, there has been a major desire to construct solid state optical devices that operate in the limit where …

Design and synthesis of conjugated macrocycles and polymers
… relative to the classic J-aggregating cyanine dyes. A variation on the dibenzanthracene theme was extended to the work described in Chapter 4, which features poly(aryleneethynylene)s containing dibenz[a,h]anthracene repeat units. These polymers have unusual stair-stepped structures that …

Effects of Metallic Nanoalloys on Dye Fluorescence
… to double or triple the emission intensity of cyanine dyes which are commonly used in (deoxyribonucleic acid) DNA microarrays. The emission intensity of indocyanine green — widely used as a contrast agent in medical imaging — was about twenty times higher in the proximity of SIFs. This …

Cyaninfarbstoffe als Fluoreszenzsonden in biomimetischen und biologischen Systemen : Fluoreszenz-Korrelations-Spektroskopie und Fluoreszenzanisotropie-Untersuchungen
Um Prozesse in biologischen Systemen auf molekularer Ebene zu untersuchen, haben sich vor allem fluoreszenzspektroskopische Methoden bewährt. Die Möglichkeit, einzelne Moleküle zu beobachten, hat zu einem deutlichen Fortschritt im Verständnis von elementaren biochemischen Prozessen geführt. Zu …
