A novel D-A type terpyridine-based carbazole Zn(II) complex with enhanced two-photon absorption and its bioimaging application

Comparison of Carbazole and Fluorene Donating Effects on the Two‐Photon Absorption and Nitric Oxide Photorelease Capabilities of a Ruthenium–Nitrosyl Complex

“…[18] Its synthesis involved first brominating the carbazole by using DMF as solvent, after which alkylation was performed by a novel methodology [19] involving water, sodium hydroxide, and a phase-transfer catalyst (tetrabutylammonium iodide) at 30°C with vigorous stirring for 24 h resulting in the pure product B after recrystallization. This approach avoided the use of organic solvents like DMF that are normally used for the alkylation of carbazole as well as the harsh reagent NaH.…”

Nanomolar pyrophosphate detection and nucleus staining in living cells with simple terpyridine–Zn(II) complexes

“…As mentioned, CZtpyZn mainly stained nucleus while AMtpyZn mapping a whole cell. Previous reports have illustrated that terpyridine derivatives ligands and their Zn(II) complexes bearing two terpyridine ligands were not capable of staining nucleus but only cytoplasm 37 38 . They are not able to coordinate with PPi or other species in nucleus.…”

“…Recently, terpyridine derivatives and their Zn(II) complexes have emerged as one–photon and two–photon dyes used in bioimaging due to their rich photophysical properties 35 36 37 38 . Terpyridine derivatives can also be used for constructing many kinds of supramolecular assemblies with metal ions such as Zn 2+ , known as coordination–driven self–assembly 39 40 41 42 43 44 .…”

Carbazole‐Terpyridine Donor‐Acceptor Dyads with Rigid π‐Conjugated Bridges

“…A vast number of derivatives containing carbazole or terpyridine units can be found in the literature, but relatively few reports on compounds carrying both units separated by a π–conjugated system . Therefore, there is room for developing new carbazole‐terpyridine derivatives with enhanced optoelectronic features, also to widen our knowledge on the relationship between the structure and the electronic properties .…”

“…A vast number of derivatives containing carbazole or terpyridine units can be found in the literature, but relatively few reports on compounds carrying both units separated by a π-conjugated system. [42][43][44][45][46][47] Therefore, there is room for developing new carbazole-terpyridine derivatives with enhanced optoelectronic features, also to widen our knowledge on the relationship between the structure and the electronic properties. [48] Our earlier work carried out on this type of molecules showed that the absorption and emission properties of carbazole-terpyridine dyads can be finely tuned by changing the spacers between the two terminal subunits.…”
