Photoisomerisation has been shown to be an efficient excited-state relaxation mechanism for a variety of nature-based and artificial-based molecular systems. Here we report on the excited-state relaxation dynamics and consequent photostability of a symmet

Starting from 4-bromobenzaldehyde or 1,4-benzenedicarboxaldehyde, two new poly(p-phenylenevinylene) derivatives P1 and P2 were synthesized by a five-step synthetic route. These fully conjugated polymers contain 1 or 2 oxadiazole rings and 3 or 4 vinylene bonds per repeat unit for P1 and P2, respectively, and were amorphous and soluble in common organic solvents. The Tg values were 28°C for P1 and 57°C for P2. The polymers emitted greenish-blue light in solution with photoluminescence (PL) emission maximum at 487-511 nm and yellowish-green light with PL emission maximum at 515-558 nm in thin films. Electroluminescence (EL) was achieved from single-layer LEDs of polymer P1 with the configuration ITO/PEDOT/P1/Al with voltage-tunable EL colors from 558 nm (9 V) to 527 nm (16 V). The observed EL spectral blue shift with increasing voltage is a result of conformational changes of the polymer backbone with increase in temperature, as evidenced from the absorption and PL spectra changes upon annealing of P1 thin films at different temperatures.

A detailed description is provided for a new general approach that allows production of amplified amounts of effective noncovalent binders from pools of compounds that can exist in a dynamic equilibrium. This approach involves a) selective binding of the
Synthesis of p-Phenylene-di-Acrylyl-Bis-N-Phenyl (PAPHA), Fumaryl-Bis-N-Phenyl (FPHA), Isophthalyl-Bis-N-Phenyl (IPHA) Hydroxamic Acids and Spectral and Magnetic Studies of their Polymers with Mn(II), Fe(II), Co(II), Ni(II), Cu(II) and Zn(II)

Three new bis-ligands, PAPHA, FPHA and IPHA have been synthesized and their polymers with Mn(II), Fe(II), Co(II), Ni(II), Cu(II) and Zn(II) have been prepared.The compositions of the polymers have been proposed on the basis of elemental analysis, and their infrared and electronic spectra and magnetic susceptibilities have been reported.On the basis of these observations, their structures have been discussed.
