Hyperbranched polyynes: syntheses, photoluminescence, light refraction, thermal curing, metal complexation, pyrolytic ceramization, and soft magnetization
Article Abstract:
The possibility of using triynes [R(C triple bond CH)3] as monomer units to assemble hyperbranched polyynes is explored. A group of hyperbranched polyynes (hb-PYs) is prepared through structural design and reaction control, which are soluble, emissive, refractive, thermally curable, peripherally functionalizable, and molecularly metallizable.

Spectroscopic study and simulation from recent structural models for eumelanin: II. Oligomers
Article Abstract:
Experiments on the spectroscopic simulations of a leading structural model for melanin, responsible for pigment coloration and photo protection in humans and animals are conducted. A linear combination of the oligomeric spectra reproducing several features of the experimental spectrum is also discussed.

Spectroscopic study and simulation from recent structural models for eumelanin: I. Monomer, dimers
Article Abstract:
Spectroscopic simulations of a leading structural model for melanin, the pigment responsible for coloration and photoprotection in humans and animals are investigated. The structure-function relationship for eumelanin is explored by simulating their physical and chemical properties.
