“…Naphthalene-based molecules attribute large band gaps; hence, these are suitable for blue luminescence. Accordingly, naphthalene-containing polymers were developed for blue emitting OLEDs. − Compared to small molecules, polymers with high molecular weight are preferred for device fabrication since small molecules tend to crystallize and phase segregate within devices . Although naphthalene-based small molecules are reported for pure blue electroluminescent properties, to the best of our knowledge naphthalene-based polymers with high molecular weight for the same are hitherto unknown.…”

Efficient light emitting diodes (LEDs) derived from organic π-conjugated polymers are in the center of light generating research. Facile fabrication of true color blue LEDs is challenging. Herein, for the first time, we report the synthesis of highly soluble new π-conjugated polymers 1,4-polynaphthalenes with high molecular weight following a Ni(0)-mediated Yamamoto coupling reaction. The designed polymer shows a color pure blue luminescence with a high quantum yield of ∼80% in solution and ∼34% in thin film. We demonstrate solution-processed fabrication and ambient condition operation of LEDs using 1,4-polynaphthalene as the active layer. True color blue electroluminescence from the LEDs with CIE coordinates (0.16, 0.08) meets the criteria of the National Television Standards Committee (NTSC) for efficient displays.

“…Among these polymers, poly(p-phenylenevinylene) (PPV) and its derivatives attracted significant attention because of their advantages such as low turn-on voltage, short switching time, high efficiency and good stability [4][5][6][7]. Similarly, poly(naphthalenevinylene) (PNV) and its derivatives [8,9] also have been synthesized as blue light emitting materials. However, PNV is insoluble in usual organic solvents such as toluene and tetrahydrofuran (THF), which limits its applications.…”

“…Particularly, the specific luminescence of conjugated polymers such as high color purity, remarkable photoluminescence (PL) efficiency, and long life time which make these materials attach much more attention. Meanwhile, compared to the inorganic materials, organic conjugated systems possess numerous advantages: they are lightweight, they consume less power, and they are inexpensiveness . In addition, these π‐conjugated polymers are generally solubility in common solvents and are easily manufacture.…”

In this report, different morphologies of poly(aryl ether)s (PAEs) fibers were prepared via an electrospinning method. It is interesting that the fibers with relatively large diameter possessed strong fluorescence intensity. Meanwhile, photoluminescence spectra indicated that the PAEs fibers exhibited the following luminescence characteristics (excitation wavelength (nm); color): 330‐380, blue and 450‐490, green. The color stability in solid state could be attributed to the chromophore and proper inter‐chain aggregation. The water contact angle of fiber membrane was improved compared to that of flat film, it could reach to the 158°. The hydrophobic and superhydrophobic of electrospun membrane were mainly caused by the rough surface. Moreover, these PAEs fibers also showed excellent thermal stability with glass‐transition temperatures in the range of 251‐298°C, 10% weight loss temperatures in the range of 534‐558°C, and the weight residue more than 53% at 800°C in nitrogen. This study extended a potential application in special textiles, optoelectronic sensors, and optical detectors. POLYM. ENG. SCI., 58:1945–1954, 2018. © 2017 Society of Plastics Engineers
