Synthesis and characterization of polyketanils with 3,8-diamino-6-phenylphenanthridine moieties exhibiting light emitting properties

Enhanced power conversion efficiency in bulk heterojunction solar cell based on new polyazomethine with vinylene moieties and [6,6]-phenyl C61 butyric acid methyl ester by adding 10-camphorsulfonic acid

“…This behaviour could be probably explained by the fact that CSA place double role in the active layer and not only protonated polyazomethine but also could created hydrogen bonding between CSA molecules. Similar work was observed by Iwan et al [30,31] for polyketanils protonated with various acids. However, to confirm this prediction additional work is required.…”

“…This implies that acid-base chemistry could be used for the modification of polymer properties. At past some researchers applied acid-base chemistry to change photoluminescence properties of polyazomethines and polyketanils [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39]. Bathochromic or hypsochromic shift at the maximum of absorption and emission bands were found for polymers after protonation depend from chemical structure of PAZ, kind of dopant and solvent used [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39].…”

Crystal Structure Determination of 4-[(Di-p-tolyl-amino)-benzylidene]-(5-pyridin-4-yl-[1,3,4]thiadiazol-2-yl)-imine along with Selected Properties of Imine in Neutral and Protonated Form with Camforosulphonic Acid: Theoretical and Experimental Studies

“…It should be emphasized that imines are extensively studied group of materials due to tunability of their thermal, optical and electrical properties, adding adequate protonating agent [ 8 , 9 , 10 , 11 ]. In our previous research [ 12 ] we described that polyketanils with 3,8-diamino-6-phenylphenanthridine groups doped with CSA and methanesulfonic acid (MSA) change their photoluminescence properties differently, depending on used solvent. It was found that both CSA and MSA interacted mainly with the nitrogen in phenanthridine ring of the polyketanils.…”

Polyazomethine with vinylene and phenantridine moieties in the main chain: Synthesis, characterization, opto(electrical) properties and theoretical calculations

“…12 On the other hand, polyazomethines based on 3,8-diamino-6-phenylphenanthridine (DAPP) have also been seldom studied. 13,14 The present authors' former works describe photoluminescence and the structural properties of polyketimines synthesized via polycondensation of various diketones with 3,8-diamino-6-phenylphenanthridine. 13,14 The emission spectra of polymers obtained from 3,8-diamino-6-phenylphenanthridine and trans-1,2-dibenzoylethylene, p-dibenzoylbenzene and dibenzyl showed maximum in the range 510-520 nm.…”

The large phenyl side group present in DAPP along the polymer chain can reduce the crystallinity and increase the solubility of the polyazomethines.…”
