“…В нейтральной (нелегированной) форме они являются полупроводниками и могут быть использованы в качестве активных компонентов «пла-стиковой электроники», [60,61], в полимерных светодиодах [62,63], полимерных лазерах, фотоэлементах, полевых транзисторах, огнезащитных материалах и т.д. Недавно были опубликованы результаты исследований, демонстрирующие использование полиазометинов в нанокомпозитных материалах с углеродными нанотрубками [64][65][66][67], в полимерах, способных формировать квантовые точки [68] и материалах с дырочной проводимостью [69]. С их помощью можно проводить исследования ширины запрещенной зоны [70].…”

“…Schiff base polymers also called polyimines or polyazomethines (CH=N) have been the subject of interest from last several decades and prepared by the polycondensation reaction of carbonyl compounds (dialdehydes or diketones) with aliphatic or aromatic diamines. [1][2][3] The researchers are attracted towards the synthesis of new polyimines because of their advantageous properties such as liquid-crystalline, 4 fluorescence, 5,6 optical and electronic properties, 7,8 high thermal stability, 9,10 fiber forming, 11,12 thin film forming, [13][14][15] coordination abilities with metal ions 16 and antimicrobial activities. 17,18 These properties make them important candidate for application in solar cells, 19,20 optoelectronic sensors, 21 photo-luminescent devices, 22 aerospace, 23 packaging materials and antifouling paints.…”

Three new aliphatic-aromatic polymers having naphthyl rings were prepared by the polycondenstion of dialdehydes or diketone monomers with 1,5-naphthalenediamine or 1,4-phenylenediamine. The monomers were prepared by the reaction of aromatic aldehyde or ketone with 1,6-dibromohexane. The molecular mass of the monomers was confirmed through E.I mass spectroscopy. The structures of monomers and polymers were characterized by 1 HNMR, FT-IR, UV-Vis Spectroscopy, SEM and TG/DTA. Fluorescence emissions of monomers and polymers were recorded and their quantum yields were calculated, all the compounds showed fluorescence property and indicated violet, blue-green, orange and red light emissions. The quantum yields of the polymers were obtained within the range of 0.04 to 24.3%. The semicrystalline and amorphous nature of the polymers was analyzed through powdered X-ray diffraction. Antimicrobial activities of the polymers were examined against different bacterial and fungal species. Thin film forming ability of the synthesized polymers was evaluated by making their blends with PVC (poly vinyl chloride) in different w/w% ratios.

“…By taking the advantage of these features, PAM has potential applications in electronics, optoelectronics and photonics. Our group has carried out some studies on the design and synthesis of PAMs for multifunction of optical, electrochemical, acidochromic and electrochromic properties [14][15][16][17][18] .…”
