Poly A-vinylcarbazole

Other materials which appear to be suitable as active battery el trodes are polyazulene poly (A-vinylcarbazole) polyquinolines and, most recently, polyaniline (PANI) panI, in particular, is a promising material for the... 

ErQ3 gives both PL and EL emission at 1,500 nm.207-209 Red light (614 nm) is emitted by [Eu(TTFA)3(phen)] (Figure 2(a)) doped in a poly(A-vinylcarbazole) layer.210 The complex [Eu(TTFA)3(TPPO)2] (TPPO = triphenylphosphine oxide, see Figure 2(f)) emits in the red when incorporated in OLEDs,211,212 behavior which is enhanced when the material is heat treated.204 Near-IR EL and PL emission was observed from blends of polyfp-phenylene-vinylene) with [Yb(TPP)(ACAC)] and [Er(TPP)(ACAC)] (H2TPP is 5,10,15,20-tetraphenylporphyrin) by both EL and PL 213...

Note 3 A polymer showing a substantial increase in electric conductivity upon irradiation with ultraviolet or visible light is called a photoconductive polymer an example is poly(A-vinylcarbazole) (see [2], p. 302 for photoconductivity). 

Some polymeric materials become conductive when illuminated with light. For instance, poly(A -vinylcarbazole) is an insulator in the dark, but when exposed to UV radiation it becomes conductive. Addition of electron acceptors and sensitizing dyes allows the photoconductive response to be extended into the visible and near-IR (NIR) regions. In general, such photoconductivity is dependent on the material s ability to create free-charge carriers, electron holes, through absorption of light, and to move these carriers when a current is applied.

Polymers produced by cationic vinyl polymerizations include poly(A/-vinylcarbazole) and poly(vinyl ether). However, polyisobutylene and its copolymer with isoprene (butyl rubber) is probably the most important commercial polymer produced by a cationic polymerization. Other industrial polymers such as poly(styrene) can be prepared by cationic polymerization, although they are usually produced radically or anionically. Many low molecular weight polymers produced by cationic polymerizations of...

In this context, the polymerization kinetic of MMA, under light irradiation, using a CT complex between a polymeric donor such as poly(A -vinylcarbazole) [poly(NVC)] and bromine as the acceptor has been investigated [69]. A radical mechanism for the polymerization is suggested. Moreover, the presence of bromine atoms as end groiqjs in the obtained poly(MMA) and the lack of any evidence of poly(NVC) chemically linked to poly(MMA) have allowed the authors to propose that the radical generation process may be described as in Scheme 11 ...

The quenching of triplet excitons on poly(A -vinylcarbazole) by biacetyl has also been examined and delayed fluorescence (20—50 ns) observed indicating some exciton mobility occurs even after triplet-triplet annihilation has become insignificant. " An exciton-trapping model is used to describe the results. Further...

The most important class belongs to polymers based on A-vinylcarb-azole (NVK). Carbazole polymers are reviewed in the literature. The interest in poly(A-vinylcarbazole) (PVK) and related polymers originates because these polymers are ...
