Hexagonal boron nitride quantum dot (BNQD) has aroused great interest in the optoelectronics field due to their metal-free nature with promising optical properties. However, it has been a great challenge to modulate its photoluminescence to the long-wavelength region so far. Herein, BNQDs with full-color emission (420−610 nm) have been implemented by doping diverse amino ligands in different solvents for the first attempt. This color variation from blue, green, yellow-green, yellow to red is ascribed to the surface states tunable via amination degree. Attractively, the quantum yield of our blue BNQDs has set a record at 32.27%, and rare yellow-green BNQDs have been demonstrated. Combining good thermal dissipation capability and high transparency, our fullcolor BNQD holds great potential for transparent flexible display and security labels at the elevated temperature.

In dilute aqueous solution, micelle-forming sodium hexadecylimino diacetate assembles into vesicles induced by Cu(II), Co(II) and Ni(II) ions.

Chemical dehydrochlorination of 1,1,1-and 1,1,2-trichloroethanes with anhydrous potassium hydroxide (KOH) in the presence of a poly(ethylene glycol) oligomer as phase transfer catalyst leads to polymeric carbons with partly carbynoid structures. The FTIR spectra show a strong band at 2130 cm Ϫ1 and FT-Raman exhibits a strong line at around 1900 cm Ϫ1, either of which is interpreted as the C'COC stretching mode of the linear carbon chain with alternating carbon-carbon triple and single bonds (polyyne). Carbons prepared by this technique are amorphous nanoparticles with diameters in the 30 -50 range nm. After iodine doping they have dc conductivities of 10 Ϫ3 S cm Ϫ1 .
