Electron donating poly(2,7-carbazoles) are one of the most attractive materials emerged as p-type semiconductors for applications in photovoltaic devices in combination with relevant electron accepting systems. On the other ...

In this study, chitosan was grafted with poly[(2-diethyl amino)ethyl methacrylate] in homogeneous and heterogeneous systems by using potassium persulphate as the initiator. The effect of temperature, time, (2-diethyl ...

Iodine releasing polymer films were prepared by blending the polysaccharide pullulan (PUL) with poly(vinyl pyrrolidone) (PVP) and poly(vinyl alcohol) (PVA) while glutaraldehyde (GA) was used as a cross linker and glycerine ...

Graft copolymerization of bis (2-methacryloyl oxy ethyl) acid phosphate (BAP) on to chitosan initiated by potassium per sulphate (KPS) under N2 atmosphere has been studied. The effect of polymer concentration, monomer ...

Chitosan was modified using citric anhydride to produce film membranes via solvent evaporation. The films dissolved in acidic media which showed that crosslinking was not achieved, but it showed an appreciable amount of ...

π-Conjugated light emitting polymers are having very wide applications in many areas, especially in optoelectronic, photonic and renewable energy systems. 2,7-substituted polycarbazoles are excellent p-type candidates with ...

Perylene chromophoric derivatives are versatile compounds for many applications in various fields. Excellent optical properties such as high extinction coefficients and strong fluorescence combined with ease in electron ...
