Preparation and near-infrared optical limiting property of fluorene-containing functional polyacetylene
A novel functional polyacetylene containing fluorene group as a pendant, poly(2-( p-methylstyrene)-7-acetylene-9,9-dioctylfluorene), was synthesized in moderate yield by [Rh(nbd)Cl]2-Et3N catalyst. The structures and properties of monomer and polymer were characterized and evaluated with FTIR, NMR, UV–vis, GPC and Z-scan, respectively. The results show that the incorporation of f...

Theoretical Study of Structures and Optical Absorption of Si172 Quantum Dots
The structures and optical properties of silicon quantum dots (QDs) have long been studied. Exploring the growth pattern of silicon crystal is challenging due to the competitions among various structural motifs. Here, about 1.7 ~ 1.9 nm silicon QDs (Si172 QDs) have been unbiased searched by genetic algorithm (GA) combined with a tight-binding molecul...

70. Facile one-pot synthesis of fluorescent hyperbranched polymers for optical detection of glucose
Fluorescent and glucose-sensitive hyperbranched poly(amidoamine)s (HPAMAMs-B) were synthesized via Michael addition of 1-(2-aminoethyl) piperazine (AEPZ), methyl acrylate (MA), and 3-aminobenzeneboronic acid (APBA). These hyperbranched polymers emitted chartreuse photoluminescence and showed emission band at 378 nm under excitation wavelength. The intensity of emission band was enhanced with incre...

A photocatalytic reactor derived from microstructured polymer optical fiber preform
This paper reports a novel photocatalytic reactor having 547 pieces of TiO2 nanocrystal-film-modified capillaries, which is derived from a microstructured polymer optical fiber (MPOF) preform. The photocatalytic active TiO2 nanocrystal film is obtained by microwave processing of the TiO2 gel films in the MPOF preform. The MPOF preform not only plays a role as a light-transmitting media, also a TiO...

Substituted graphene nano-flakes: Defective structure and large nonlinear optical property
Substituted graphenes without centrosymmetry can be considered as a new acceptor-graphene model for
NLO materials and exhibit large static first hyperpolarizabilities (b0). Especially, three interesting relationships
between the defect structure and b0 value are observed. We found that the defects (for example,
the Stone–Wales and 585 defects) in graphenes can greatly enhance b0 values up...

Lithium salt of end-substituted nanotube: Structure and large nonlinear optical property
Lithium salt of substituted nanotube is suggested as a new kind of nonlinear optical (NLO) material. It is
found that the combination of the lithiation effect and the donor substitution effect can greatly enhance
the static first hyperpolarizability (b0). Specially, the unusual donor – acceptor(nanotube) – donor system
Li–NT(6,0)–(NH2)2 has considerable b0 to be 6.8 10...

What is the role of defects in single-walled carbon nanotubes for nonlinear optical property?
In carbon nanotubes (CNTs), there exist various kinds of defects which may influence the electrical,
thermal and mechanical properties of carbon nanotubes. However, how the defect influences the
nonlinear optical (NLO) property is still unknown.
